can it be possible to think that way way back....?

Well... maybe. Very highly unlikely. If the planets in the Solar System had life then they would probably have life now. Like we do. :)
 
I think so, but I think that climate change and seas evaporating and stuff has killed them off and I think the same will happen to earth too.
 
It can be possible to think anything... It is very very very possible that another planet in the universe has life. It is also possible that there was life on a planet, mars, which had life.
 
Depends which other planets you're talking about.

Within the solar system, apart from an outside chance of ancient life on Mars hinted at a few years ago (which no-one seems to talk about now, so I'd imagine the evidence turned out to be less supportive than first thought) there's minimal chance at all. Venus is far too hot. Mercury is either far too hot or far too cold depending on which side of the planet you're on. And it's not as if they used to have orbits further away from the sun.

There's no chance of the gas giants having it.

BUT, when you say other planets, if you mean planets orbiting other stars, then it's VERY possible. Not only that, it's possible there's still life on some of them. But those planets are so far away we'd struggle to detect life on them, never mind contact it. In fact 20 years ago we couldn't really detect planets outside of the solar system at all.

There's another possibility though. Not a planet, but one of Jupiter's moons (I forget which one, it may be Europa or Titan) which just might possibly have had water. If it had water there's always a slim chance that it had life of some sort.
 
I bet the little martians on mars ask the same question. DO you think there's creatures living on earth, venus, pluto, the moon?!
 
There actually probably was, but not like little green men or anything, more like microbial life (bacterias and such).
The fact that there was at one time liquid water flowing on mars, and that mars did have a hot core and volcanic activity suggests that hardy microbes could have possibly flourished.
Once Mars's core hardened there was no longer a magnetic field protecting the surface which let violent solar radiation to penetrate the life forms and kill them, there isn't any solid proof that there was any life on mars to begin with, but it was possible.
There probably isn't any life in our solar system now, except on Earth, but some scientist believe that one of Jupiter's moons (Europa) could be harboring life under its protective ice shield, but that is purely theoretical.
