Yes of course, but what do do know is that life is robust and adaptable. Earth itself contains a huge variety of different environments... and there is significant evidence to show that the earth atmosphere has actually changed because of life... in fact life exists in the most unlikely of places.. this shows at the very least that you could alter earths environmental conditions by a fairly large margin and still some life would thrive.stemann said:This assumes that life can survive on methane. Maybe life can only survive in certain conditions and is very, very rare. This does not mean it has great value though. If we were the only life in the universe it isn't great evidence for God, just that life is one of those things that only exists in very rare conditions.
What if there was a certain element only avaible in one tiny section of the universe? Does this prove that God created the universe just for that element? Religion puts conscious sentient life above all else. I don't, perhaps because I am a scientist in the first place.
It could be that the only difference between earth and a trillion other places life could have occured is that abiogenesis happened here. That could be what makes earth special.. or.. we might just find microbacteria on Mars.. or elsewhere.
