I, for one, am not questioning that evidence. I believe there was a Big Bang. It seems to have happened about thirteen and a half billion years ago.
But the universe is also, in a different way, eternal.
You see, one of the things that began in the Big Bang was time. There was no time before the Big Bang, so there was no 'before'. As far as time is concerned -- and I'm not concerned here with definitions of time, any definition will do -- the universe has always existed.
I believe the 'law of biogenesis' is a creationist expression used to mean that life cannot come from non-life. So what you're asking me is whether anyone has seen life arise from non-life.
Well, there's no chance of that, is there? Do you know what life is? Life is organic chemicals -- proteins and amino acids and stuff. The simplest forms of life are viruses -- some would argue that they aren't strictly life at all. A virus is just a bit of RNA or DNA wrapped in a protein coat. One step down from that -- into non-life -- would be individual proteins and other complex organic molecules.
Biochemists have polysyllabic names for thousands of these molecules, but life, as a rule, knows them by a single name:
Food.
Any life trying to evolve from non-life on planet Earth today would be gobbled up before it ever got going.
Life from non-life only happened once. We know this because all life today is genetically related -- it all dates back to a single ancestor. The original badass, as Neil Stephenson called it.
My apologies, Ma'am your Honour. I can't show the court the evidence for abiogenesis. The defendant ate it.
i know probability isnt everything but thats where abiogenesis is a weird field.
in most fields, if you are trying to figure out a process with a goal in mind, usually the finished product isnt made yet...
claiming that "god created life" is unscientific IS initself unscientific.
THE PROBLEM WITH DEBATING CREATIONISTS: You CANNOT reason a person OUT of position that they did not REASON themselves into.
then forensics isn't science either. you cannot directly observe the events involved in forensics, but you can indirectly, just like in evolution.
with science you do not have to witness the event happening, just the evidence that it happened. you can demonstrate evolution and you can test it. clearly you haven't read a single link i've posted on those issues.
...and if they don't get an answer that's within the dating range, they go onto a different method
seriously, if you try potassium-argon dating on a bone that's either too old or too young for it, you get a result that's obviously wrong.
...the scientific method is a tiny bit older than that. and it's stood the test of time, as the computer you're working on can attest to.
then practice what you preach and realize that evolution is the logical answer that we can understand.
it doesn't matter where it came from, it's still 4 billion years old
no, it isn't. you're entirely misrepresenting the theory of evolution just to make evolution seem absurd...
which is basically the only way you can make such a well-established theory look that way.
...and you just choose personal attacks.
i didn't ignore any supposed evidence, i systematically refuted it.
...i don't have to trust what a scientist said (unlike the people who are directly trusting what a book said), there is a mountain of evidence i can look at that supports it.
...all you have is a bunch of claims that you cannot back up
you have no science, evolution is the only science here.

Gravity clumps matter together. The clumped matter exerts more gravitational force and attracts yet more matter to itself. Thus we get dust-clouds, stars, planets and so on. Energy transforms matter. Some transformations last longer than others and are further transformed. These processes average out over the entire universe in thermodynamic terms, but at the scale on which we apprehend reality, its operations are discrete -- some arrangements of matter are locally preferred over others, certain systems become locally self-sustaining over long periods of time while others don't. The organization we see in the universe arises from -- in fact, is -- this localized selectivity. You would call that God. I just call it inevitable.
Natural selection and abiogenesis are not processes with a goal in mind. They are no more teleological than the law of gravity.
Claiming 'God created life' is only unscientific if you offer no valid evidence for it. Thus we return to the thread topic -- proponents of intelligent design must admit their defeat, at least till now, since they have been unable to offer any unfalsifiable proof of this claim.

Wow for a so called scientist type, you have no idea how C14 is formed do you.....
C14 is assumed to be formed by a constant "growth" C14 into the cell of living tissue based on a constant sunshine factor, and can be screwed up by variation in solar output, er (sunspots, flares). Next C14 is also affected by fire, that means not direct fire just close-to fire.
If such dating methods were truely scientific, they would not be expressed in ranges of years. An assumed approximation of age.......These guesses are usually in the range of 100's of years..........
If such science was used to orbit the shuttle, it would go to the moon or mars and be deemed close enough...........

there are problems with that theory which does have evidence to back it up. entropy comes to mind, the universe have an entropy from order to chaos. your right about clumping but that falls into entropy.
the problem with life is that it is astronomical in its complexity which is so obviously contrary to entropy
the ONLY way some scientist have tried to explain around this is emergence.
im not sure i agree (that natural selection and abiogenesis are not processes with a goal in mind, no more teleological than the law of gravity). i always thought of abiogenesis more as reverse engineering
how would you prove that god (or something) was involved (in the creation of life)? what would the evidence look like?
in the human body it's present in the same amount that it is in the atmosphere
Just because you think it's reason doesn't make it so. Clearly you ignored a metric buttload of evidence for evolution, and clung on to flimsy wishes regarding creationism. There is no logical way anyone can weigh up the evidence for both and pick creationism (hint: because there is no evidence at all for creationism, and a heck of a lot for evolution).
So, please don't try to pull that "I'm a rational creationist" stuff, as that's a contradiction in terms, regardless of how sincere you feel about it.
I'm glad you picked that phrase -- 'astronomical in its compexity'. If the Second Law of Thermodynamics operated the way you say, there would be no complex structure in the universe: no galaxies, stars or planets. Mass and energy would be equally distributed throughout space, and the Big Bang would have been immediately succeeded by the Big Fizzle; the universe as we know it would never have come into existence.
The Second Law of Thermodynamics has been accepted in science since the 1820s. If it contradicted the existence of the universe, it would hardly have lasted so long, would it?
In principle, it's easy: just demonstrate scientifically that such-and-such a phenomenon cannot have come about through the normal operations of nature or as a result of human intervention. Once these two operators are conclusively excluded, all you have left is God.
funny how a few simple scientific facts can debunk your theory entirely.
thats not how entropy works. its universal. it gives us the perseption that time goes one way. and egg if dropped will always break, a broken egg will never assemble into a whole. order to chaos always unless interfered with

Remember what I said: 'These processes average out over the entire universe in thermodynamic terms'. A decrease in entropy in one location is made up for by an equivalent increase elsewhere.

This is incorrect, since there is nothing to 'explain around'.
yes there is, life is reverse entropy. incredible order despite a push for chaos
Emergence is simply the issue of how complex systems, or systems interacting with other systems, can have properties not shared by their component parts. Emergent properties are not proof of a designer.
your right, i agree with you. never claimed it was. emergence is a facinating way in which something simple connects with other simples and forms into something complex with no designer.
im not sure i agree (that natural selection and abiogenesis are not processes with a goal in mind, no more teleological than the law of gravity). i always thought of abiogenesis more as reverse engineering
I am afraid there is no room for disagreement, only for misunderstanding, because these are strictly-defined terms in science and philosophy. We can't just use them to mean whatever we like.
surely you can see my reasoning though, abiogenesis is trying to explain how life can form by accident, independant of a creator correct? life exists, so we know that accident or god, we are here. isnt that reverse engineering?
how would you prove that god (or something) was involved (in the creation of life)? what would the evidence look like?
That is precisely the question I'm asking creationists on my Proof of ID thread.

i agree with your reasoning... its logical. but i simply dont see evidence that life could exist through natural processes. its just too complex (even single cellular lifeforms)

You must pardon me for being so blunt, but those really are the facts. If you would read up a little on thermodynamics and entropy instead of trusting to creationist websites and books for your 'scientific' information, you would immediately realize that it is so.
The rate of decay of 14C is such that half of an amount will convert back to 14N in 5,730 years (plus or minus 40 years). This is the “half-life.” So, in two half-lives, or 11,460 years, only one-quarter of that in living organisms at present, then it has a theoretical age of 11,460 years. Anything over about 50,000 years old, should theoretically have no detectable 14C left. That is why radiocarbon dating cannot give millions of years. In fact, if a sample contains 14C, it is good evidence that it is not millions of years old.
However, things are not quite so simple. First, plants discriminate against carbon dioxide containing 14C. That is, they take up less than would be expected and so they test older than they really are. Furthermore, different types of plants discriminate differently. This also has to be corrected for.[2]
Second, the ratio of 14C/12C in the atmosphere has not been constant—for example, it was higher before the industrial era when the massive burning of fossil fuels released a lot of carbon dioxide that was depleted in 14C. This would make things which died at that time appear older in terms of carbon dating. Then there was a rise in 14CO2 with the advent of atmospheric testing of atomic bombs in the 1950s.[3] This would make things carbon-dated from that time appear younger than their true age.
Measurement of 14C in historically dated objects (e.g., seeds in the graves of historically dated tombs) enables the level of 14C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible. Accordingly, carbon dating carefully applied to items from historical times can be useful. However, even with such historical calibration, archaeologists do not regard 14C dates as absolute because of frequent anomalies. They rely more on dating methods that link into historical records.
The amount of cosmic rays penetrating the earth's atmosphere affects the amount of 14C produced and therefore dating the system. The amount of cosmic rays reaching the earth varies with the sun's activity, and with the earth's passage through magnetic clouds as the solar system travels around the Milky Way galaxy.
The strength of the earth's magnetic field affects the amount of cosmic rays entering the atmosphere. A stronger magnetic field deflects more cosmic rays away from the earth. Overall, the energy of the earth's magnetic field has been decreasing,[5] so more 14C is being produced now than in the past. This will make old things look older than they really are.
