(Ha, that's my fave song!)
Anyways, most scientists believe in evolution, so why do they look for other planets like ours for life? I mean, if I belived in evolution I would think that life could be anywhere, they just evolved to breath fumes that are noxoius to us or they evolved to live in 1000+ degrees F. Or am I missing something?

Yea its a good song by David Bowie.I quite like it myself.

Anyway there is no life on Mars because there is probaly/definlty no enough oxygen there and no water except maybe the sea of tranquillity and other stuff but thats not water.And I think that only the mars rover can live up there or else it just explodes after awhile.And all Mars really is, is a red planet with a red dusty surface.

Well, life on Mars has been mentioned somewhere else in the depths of another thread but right now, I can't remember where!

Nevermind...to answer your question Captain_EO, the mechanisms of evolution would grant fantastical adaptations but only if the organism survives long enough for that to take effect. But sometimes it ends up in places and just...dies because the conditions are too harsh.

I do think that our definition of "life" when it comes to "other planets" can be too restrictive (this narrow conceptual band termed the life zone being the source of the extremely slim probability that there's other life elsewhere)...but on the flip side, if we expand this definition, how are we to recognise the potential or the existence of life elsewhere?

Who says that life needs to be carbon based like us? Its possible that there could be Silicone based living things that drink Mercury and breath Chlorine. Who knows?

They don't even have to "drink" or "breathe"! Or "see" or "hear" or...

Waaah, brain explode!

Hibbert: Is the alien carbon-based, or silicone-based?
Homer: Uhhh... the second one. Zillifone. Next question?
Barney: [drunk] Is the alien Santa Claus?
Homer: Uh... yes!
Ned: Uh, where you on my roof last night stealing my weather vane?
Homer: This interview is over! *slam* *CRASH!*

Ya thats true. You know all of the alien movies, depict aliens as similar to humans as you could possibly get. I don't think and extra terrestrial life will have any resemblance to anything on earth. And if they do, then I really don't want to meet them. All they have to do is come on our planet and we will all die of some new disease that we do not have immunities to, and vice versa.

That's of course if microbiota interact with them the same way that they do us.

I suppose in a conceptual sense it wouldn't be unreasonable to assume that if beings resembled us in a physiological sense they'd come from conditions similar to ours, and therefore would likely have similar systems ==> microbiota. And that would be nasty.

You know, I'm actually trying to write a sci-fi novel which explores this topic in some depth, seeing as I'm trying to see if somebody could actually address the question of "what is life", or failing that, "what are the common elements to 'life'" (as in, I'm 80000 words in, so not just one of those "oh I bet I can write a novel anyday darn this is too hard" kind of whims, but a serious commitment).

Needless to say I'm finding it difficult.

Ya by saying that they resembled us I was implying that they had come from a similar world.

Thats really cool that you are writing a novel. I wish I had time to write. I began writing somewhat of a journal/biography about my life in college. My roommate is really weird so i figured I should start documenting some of the extremely stupid things he does. But I don't have time to even write a paragraph now.
