Now, there might be life somewhere else out there in the universe. It's pretty big. But you go ahead and show me how bigness creates life. You explain to me how if you have a bag full of bits of metal and you shake it long enough, it becomes a ticking watch or a sewing machine. Oh, you have to have billions of bags and shake them for billions of years, then it just happens? Now, that's ridiculous.
Until somebody finds other life, there is absolutely no reason to assume that it exists anywhere else in the universe, or ever has. Right now, it really looks like we're the only game in town.

To think we are alone is naive.

With the average age of a sun at around 10 billion years this gives enough time for a planet to produce life such as ours. For us it was about 2.5 billion years for life to evolve from single cell to multi cell and then another billion years to further evolve through fish, reptiles and then mammals, but the process has and keeps on speeding up.

At first it seemed that this was going to turn into a debate over creationism with the argument being life is too complex to "just happen." For which I would have responded. If life is too complex to "just happen," wouldn't that also apply to God?

So maybe we're just a huge cosmic fluke, and the only life anywhere. It's every bit as possible as there being life elsewhere. Alien bacteria could fly in on the next comet. But as of right now, we're the only life we know of, and it's misguided to just assume there's other life out there.

complex, double-helix Lego 10,000 miles long, inside a semi-permeable sphere of Legos, that would also have consciousness and be able to automatically reproduce itself. Quite a trick.
Loeb: I’ll mention just two brief comments from the point of view of an astronomer. The first comment is that when everything started, when the universe started, there was no water around, there was no oxygen, and there was no carbon. We are sort of an afterthought—the existence of life came about after stars burned hydrogen and made heavy elements.
And one of these stars is the sun and there was some debris left over from the formation of this star—some pieces of rock, one of which is the Earth. On the surface of the Earth, there was liquid water that allowed chemical reactions to take place and to end up as complicated, complex molecules that allowed organisms, like we are, to exist. So it seems circumstantial that complexity came out from the very simple initial conditions of the universe. But it’s not something that was pre-planned—it’s not like the universe was designed for us to exist in it.
Now the question is: are there other places where there are circumstances similar to that? The first thing that comes to mind is that it requires liquid water. So are there other places where we can find liquid water—other pieces of rock near other stars that have liquid water? Can we find evidence of that in our solar system, for example? Or can we find evidence for complex life as we know it in the way that it affects the environment, like the atmosphere, by observing other planets around other stars? That’s the common view that astronomers have on this subject. Now, it’s also possible that there is life out there in a very different way that we are not imagining. We often think about it in the context of our environment here, but you could imagine that instead of water, perhaps ammonia can be used to support complex molecules to make chemical reactions that take place and so forth.
