wow..... thats very deep.
so, according to you, water is the necessary and sufficient condition for life? comets have shittons of water... europa has shittons of water... hell, uranus and neptune each have more water than a hundred earths combined, but i dont see any life on them...
Well I was speculating.Anyways Uranus , neptune are distant planets from Sun so we may not expect the sort of life-form we are looking for.And you don't see any life there becuase , you haven't been there and completely searched the planet. Have you , haha ??
Humans haven't explored Uranus or Neptune completely till now.So you can't say they don't have any sort of life form(in past/future/present) , there is always a possibility.
And If there was water on MARS(in liquid state) ,balanced atmosphere was sort of necessary to hold it in that state.
Also water is a necessity for sustaining life form similiar to our own.With adequate amount of pH value, mineral content , etc.
Btw , who said that water alone is sufficient for known-life-form to exist , atleast I Didn't ??? SOil , Climate, temperature , atmosphere, and a lot other factors play a major role.
I was talking specifically about MARS , since it has many other similiar features alongwith traces of WATER. Maybe you should think think deeply on that.
BTW , I read in above posts that you don't like to read about fables of dead planets(or history ) , so please stay away from my comments , since they might talk about fables itself and might hurt your sentiments .
And hating history isn't such a good idea Sir.
Maybe someday they will across fossils. : p haha
All of the water that was there on Mars is not gone. It has not been proved as a dead planet yet, and there are chances that there might be simple organic or other form of life there. Humans know just about a few parts of the planet, and there can be life on polar regions or beneath the surface of Mars.
Agree with you.We barely have enough information to deny the existence of life.THere is a good possibility of microbial life forms below the surface.
However the question that scratches my brain a lot is that { if there was life on mars , something very sudden and tragic might have happened to force complete extinction }If the change was slow, species should have evolved themselves.
^^ hmmm, so why couldn't they send a rover there?? it would have been much more interesting than the rocks we see usually.....
Maybe they'll a few of them later on send but not now.
I think those rocks help in understanding and analysing lots of information about the past , and thats why they sent it. THey want to study the past.!!!
The texture,content and details of rocks and soils , help a lot in determining what happened previously. I think the rover has several sensors and devices that provide intricate and detailed information about the composition of rocks.
