how can you say water and oxygen is all we need to survive? what about climate? there's such extremes in the universe it's ridiculous, what about radiation? we wouldn't last 30 seconds in these harsh environments

...i could go on and on, would you like me to? heh

i don't buy that intelligent life forms can breathe sulfuric acid on other planets man, and deal with conditions in excess of 400 degrees C. it just doesn't make sense, i think we need to find planets with a balance like earth in order to find intelligent life, and that's near impossible. i'm pretty sure microrangisms can survive maybe in some very harsh conditions, hell look what we got going miles and miles deep in the ocean where it is freezing, lava flows down there and heats the water, life goes on, it's quite amazing. i'm sure this same thing is going on in many places in the universe.

i think the number of intelligent alien civilizations that have ever been is very low, factor time into it, and that makes the likelyhood that they are nearby and existing right now very low, i think. the universe is very very old, and we have existed for such a short time on that scale. we are a tiny little blip, ya know?
