Is there life on Mars?

of course there is life on mars,once man set down its rovers .the rovers would have carried bacteria from earth,and earth germs would also survive the trip to mars,spirit and curiosity would be crawling with them by now.
Just the same as man contaminated the moon,he has now contaminated mars.
check back in one hundred years and there will be a colony of mans germs and mans bacteria on both mars and the moon.
heat nor cold will kill them.

in fact when Niel Armstrong and his pals went to the moon they left all their rubbish that they had no more need for behind them.

Water streams on the planet confirmed, that is it...............

they had already found shapes in the mars soil where water once flowed,and there is ice caps on the planet.
sometimes I wonder was mars a planet like ours at one time in the distant past?

I think (although have no proof) that life teems the Universe but big beings that can aquire the ability to communicate over vast distances are a rarity.

It wouln't surprise me if there was life on Mars, Europa, Gannymee or Encelydous - even Pluto has a dynamic surface that could have running water.

it something to do with ridley scotts new film

As Ovalman says, given the vastness of space, their must be life elsewhere.
No idea of what form it would take but hope it is more advanced than us.

wouldn't have to be up to much so to be!
