now we all say life needs many minerals and most importantly water. we (with 3 acceptions(the moon and mars and io)) have found no water neither bacteria wich is a produces in the food chain (i may have got a few things wrong on;y cuz i just woke up).
neither on other solar systyms have we found planets capable of sustaining life. now im no conspiricy theorist or do i belive in aliens but ive benn asking myself a question for several days now. what is life forms on other planets do not need the natural recoursces we have on this earth.
just tell me ur opinion and what u think i want to ssee the reaction and if anyone knows someone from nasa tell them to read and forward this question to their other fellow scientists

Theoretically it doesn't have to be water just a liquid medium. Mars and the moon does have water but it's frozen. Though there is evidence that Mars once had liquid water.
Because of the possibility of liquid water under the icy surface of Europa there may be a chance for life there, it may even be complex life like what we find in the depths of our own ocean.

Life adapts to it's environment, so if life forms in a place with fewer resources it will adapt to being able to cope with that or die out.
I agree with all the things states before but we have only discovered a very very few planets compared to how many planets there are. So yes for now we have not found a planet like earth but the chance that we eventually will is high.
In situations like this, I enjoy pointing to the Drake Equation.
N = R* x Fp X Ne X Fe X Fi X Fc X L
where:
N = the number of civilizations in our galaxy with which communication might be possible;
and
R* = the average rate of star formation per year in our galaxy fp = the fraction of those stars that have planets ne = the average number of planets that can potentially support life per star that has planets fâ" = the fraction of the above that actually go on to develop life at some point fi = the fraction of the above that actually go on to develop intelligent life fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space L = the length of time such civilizations release detectable signals into space.
True, maybe life doesn't need water, oxygin (sp?) and all that. But, seeing as the universe is big (and by that, I mean incredibly big) it is simply easier to look for planets that are like ours. If we'd have to investigate every planet, we'd never find life. It's just easier to look for planets like ours, where we know life could exist. It simply increases changes of finding anything.

Yes, and that runs us into a problem. Finding Earth like planets is very difficult with our current method due to the size of the planet.

Aliens aren't what everybody says they are. You think aliens as if they are green munchkins or dwarfs. They could look exactly like humans for all we know.
Also as said before.. it wouldn't have to be H2O Necessarily but it would have to be some type of liquid. I have to say that I agree with Mage.
