Yes alien life could be very different, but could also be very similar.
Chemistry is chemistry, no matter where in the universe you are, there are only so many elements to work with.
If life arises on a planet with similar conditions to ours the chemistry of life will be the same.

Nope. Just look at the Antikytheria mechanism, a clockwork device over 2000 years old and still intact enough to recognize what it was. And it was made of delicate metal construction. SirMike is absolutely right, today's construction would last thousands of years largely intact and would still leave recognizable remnants tens of thousands of years into the future. The pyramids are simple stacks of stone and look at how they've held up. Construction is my field, I have over 25 years experience and training in materials technology. I don't think most people not involved in the field realize just how durable today's alloys and materials are.

If it were true (and I am not saying it is not possible) that humanity has played this tune before and has done so over and again, you would think that a little knowledge of history, archaeology, ecology, and what is known as "forest forensics" would make it all too obvious. We have some pretty dang old forests and landscapes on this green Earth and there is no such thing as a "society" without agriculture and roads or other methods of transportation that do not require "clearing" of the land. Trees may be only a few hundred years old, but soil which is moved tends to either stay put over an extended period of time or at least leave evidence of it having been moved at one time. Maybe the "big guys" know this, and that is why they are so interested in Antarctica? Maybe they are looking for evidence that some farmer dumped rocks at the edge of his field, down in Antarctica, or maybe they found it? A pile of rocks at the edge of an area of land is only one of many evidences left over to prove the land had been "worked" in the past. Imagine how many more one could think of if they put their mind to it, as I am certain the very intelligent have already done?
If you want evidence of past civilizations I suggest studying history, archaeology, and anthropology... taking notes, learning about forest growth and ecology and some geology, and then looking for what may be right in front of your face.
Civilization is only supposed to have been around for a few thousand years, right? Well, look at the landscape... Landscapes don't change that quickly. For instance, the Appalachian Mountains are supposed to be some of the oldest mountains in the world and they are still here. The Susquehanna River which runs through the Appalachians is one of the oldest rivers in the world and it is still here. So.... Do you think if someone cut a significant chunk out of one of them or a similar area there would be no evidence left?
The Appalachian Mountain chain is estimated to be some 400 million years old. I believe the fossil of "Lucy" is only 3 million years old. Are you going to tell me that if an advanced civilization of humanity once flourished on this planet you will not find all sorts of stuff carved right into or out of the Appalachians or similar mountains? Now, I am not talking pyramids or structures, but simply evidence of leveling of the ground (in the very distant past) for agriculture or urbanization or even mining activity? Look at what we do and have done to them! We have tunnels through them, railroad grades, interstates, and whole cities dug into their sides. You may not find a building but you damn sure ought to find evidence of the ground being disturbed in some shape or form! It may be hard to detect, but it should still be there. Who knows, maybe old roads turned into new streams, or old cuts in the hillside got worn down over time, but they still bare distinct trademarks of having been initially disturbed by conscious beings?
All I am saying is, if the evidence is there, it should be easy to spot, once people know where and how to look.
I don't trust the elites any more than the next guy, so there is my two cents on it. Do with my comments and suggestions what you will.

Group A might agree on a "prime directive" approach but what if Stalin had sent the first pioneers into space who found an Earth like planet with a more primitive civilization living on it? What if the Nazi's had been the first?
As of 1945, with the development of the Atom Bomb, not to mention all the rumored technology developed by the Nazi's, our civilization reached the capability of leaving our planet and traveling to other solar systems. This is why the "watchers" as they have been called by many older groups of our species, began to make themselves much more apparent again around that time. One way or another they managed to convince the people in power that following through with project Orion would be a bad idea.
I really should take this concept to its own thread as it ties into so many things and explains so many questions, historic events, etc that I could literally go into details for the next year or so on this.edit on 16-8-2011 by ecoparity because: (no reason given)

Personally, I think if you want to hit the nail on the head the key to the whole cyclical civilizations cover-up lies with the Giants.

Do you really think that humans could collectively destroy civilization and all its infrastructure to the point where there are no buildings or roads, yet some humans still survive, some of them still possessing knowledge of how to build structures and roads, yet they do nothing but draw deer on cave walls?
My friend, I think you watch too many movies. I don't think we could do that to ourselves so thoroughly. If there is a cyclical trend, then it would have to be something cataclysmic that happens TO humanity to destroy everything in a short time span. Even then, I don't know that I'd be totally convinced.

1.But what kind of destruction do you have in mind that completely wiped out every last piece of tehcnology.... that got these survivors of the great destruction to go back to making everything from scratch?
2. Even if their hi-tech toys became useless, some memory would have remained of the technology that they would have once used...but instead we had cavemen living in well... caves.
3. What about language? Survivors of a great destruction would not have completely discarded language and writing.
Language/writing would play a huge role for survivors to regroup and reorganize.
Yet, we do not see any evidence of a language that cavemen may have used.

As well as gamma ray burst,global pandemic,axis tilt,ice ages,comet impact,superstorms,mega earthquakes,massive volcanic eruptions,continental drift and we cannot rule out the possibility of earth being invaded by malevolent aliens...

What kind of destruction? There's a long list which features everything from all-out nuclear war, polar reversals, asteroid bombardment, solar flares... Any number of things can create massive flooding, tsunamis, and global destruction.

Let me put it to you guys this way: Which is more plausible. Aliens from space coming down and giving all this knowledge to primitive humans or for primitive humans arising from a much more ancient civilization? Maybe guided by survivors of a high-tech society in which they would be called Gods? Well, which is more plausible? Space aliens which are bipedal, quite humanoid, and apparently get along quite well in our gravity, atmospheric pressure and comfty Earth environment which would be Alien to them? No fear of alien microbes? No difficiulty communicating? Clarke's Law's the copout IMO.
Why is it that me and Blocula are in the minority here? Maybe because we're on to something we Shouldn't be discussing, hmmm?
