Mars?.?.?.?

Question

Doe's anyone think their's life on mars?.?

Answer 1

probably not.

Even if they find large amounts of liquid water underground, the rest of the environment is so harsh, I doubt there will be anything surviving.

Answer 2

Summary: there could be life on Mars that we put there via our landers.  There could be life on Mars that got there from Earth via a huge impact on Earth.  There could be life on Mars that started on Mars.  In any case, thriving life is mostly likely below the ground.

There is most certainly a small amount of life there.  Our various Mars landers were not completely sterilized.  There is evidence that common microbes survived 18 months on the Moon, exposed to vacuum and huge temperature swings.  Mars isn't as rude.

As for life of Martian origin, the data isn't in.  I suspect that there is.  There could be thriving colonies of life beneath the ground where liquid water very likely exists.

But even that could turn out to be related to life from Earth.  It has been shown that microbes can very likely be transported between Earth and Mars, hitch rides on asteroids.  So a big asteroid hits the Earth, sending debris from the Earth into space.  Some of that makes it to Mars in a survivable landing.  It's a great story, and appears plausible, even likely, in it's details.

So, i think it is very highly likely that there is life on Mars.

Answer 3

Quite possible, by judging there is/was liquid water on that planet. Liquid water is where the life depending on earth, we think Mars has the prerequisite ingredients for life, such as water, nutrients and energy.

Many scientists think Mars could have or had life in its history, and we are sending probes to find the answer.  I personal favor the chance of finding life on it.

Answer 4

The only possibility for life on Mars is if there are any remaining hotspots in the Martian crust and if water still exists in the Martian subsurface.  Then any remaining hotspots, probably heated by radioactives that still have water in the surrounding region could have life  IF life developed in the Martian seas a couple of billion years ago and that life successfully migrated into the crust.   Thats an awful lot of "ifs" and "coulds".  But its possible.

Life on earth seems to have survived using that strategy when  the surface got turned into an instant ocean of lava, thanks to early asteroid impacts.
