It seems like I always hear that "there couldn't have been life on "X" planet because there was never water. But it seems to me that is only life as WE know it. I just feel like yes you are not going to have a human like organism without the presence of water, but why not some other type of oraganism that somehow has spawned based on the perfect elemental availability on another planet. I dunno I'm just talking. Any thoughts?

Life? What is your definition of life?
Life on Earth is based on the remarkable ability of the DNA molecule to replicate. This have grown and evolved and so on into what we call life...
I can't even begin to guess how many other molecule chains there are that replicate... How many forms fo crystal are there?
DNA, and the component molecules are all very dependant on water, so if you mean life like us. Something we could convert to food, or hope to relate to... Then, no. "Life" can not exist without water.
If you mean simple a complex self replicating construct of higher molecules... Then , yes... There may even be some sort of crystaline life form out there right now that's wondering is Life and exist without liquid silicone...

I think it is exceptionally vain of us to believe that all life must be similar or exactly like us. Life could theoretically exist with water, oxygen, or any other requirement we have for life.
Under the same thought, that life form may require some element or substance that we don't know anything about at this point.

I have heard that some other planets had certain micro-organisms living on them. They have adapted to such conditions and are very comfortable up there. But they are not human and not like any freaky alien as we see on television with green eyes above their heads and that sort of things. They are very minute little organisms and so there is nothing humans can do with them.

Most likely not. Water is a basic need of ANY life, from plants to animals to humans.

basically you have to have a life form that is not made up of water also my partner believes that it would have to be made up of some form of energy i.e electricity that would be capable of sustaining a form of some sort.
hope this helps
as long as energy exists to create, it will find a way of producing life of some form.

Fair point. Water is just such a useful chemical though, it is hard to imagine an alternative that is not reactive, readily avaiable, and can be used to both intra- and extracellular transport.

Well, silicon based life (instead of carbon based life like us) has been theorized, and it if it exists it would probably not depend on water the way we do if at all.

if the life forms are rocklike, then no water necessary.anything whose body composition is not part water will not need water,otherwise water is a basic need.

Maybe. Over millions of years I bet we could adapt.

yes. there are beings that does not have a physical shape( like a being made of pure energy).
