Life from Mars? The Theories Continue

Just found the following story about the theory that certain life on our planet didn't evolve here because evolution engineers an organism for its environment and the only known environment that would create certain organisms found here on earth is on Mars

I theory it sounds plausible to me, but I could do with a little more information. Does anyone know much about this topic?

I think when they find life on mars people will say wow and go one with their lives. I believe they will find some microbes or something eventually. In reality it is not going to change the world unless we discovered intelligent life.

The true usefulness of space exploration to humanity is colonization of other parts of our solar system, mining and terraforming.

We need to expand into space to ensure the continuation of the only known intelligent life in the universe and for the sheer adventure of it.

Humanity needs things to inspire us to keep us from wanting to killing each other.

Learning and exploration can make a young mind a peaceful one as an adult.

Do you realize the size city we could build on Mars for a single years budget of the US military?

I believe this falls under the Panspermia theory.

I suppose I see a kind of logic in why they assume what they
have, but at the end of the day it's all still theory and conjec-
ture, as we don't really have enough proof to prove Panssper-
mia to be correct.

I think that it would be possible for life that is highly resistant
to heavy radiation to have evolved her on Earth, I seem to
remember reading a few months ago that it as ofund that life
started on Earth at an earlier time than had been previously
thought, and in much harsher conditions as well.
