It's very possible that life arose on Mars and was transferred to the Earth by a meteor impact on Mars. The scenario is that the impact kicked up debris with enough velocity to escape Mars' gravity, and microscopic life carried inside this impact meteor can survive the trip to Earth and the landing and seed it.
We've already found a meteorite in Antarctica from Mars that is 4 billion years old and has indirect evidence of microscopic life.
If the rock is not too small (to offer shielding) and not too big (totally burn up in the re-entry) spores CAN survive in space, possible for millions of years. The trip from Earth to Mars can take place in as short as a few years with the right impact.
Mars had a favorable environment billions of years ago, at the same time the Earth was still forming and may have got a couple of hundred million years of a "jump" on the earth. Life may have been transferred back and forth between the Earth, Mars and Venus (which also may have had favorable conditions; cooler and oceans that were gradually lost to space) many times.
Who knows? We all be Martians.

I disagree.
How to get from there to here? By being blasted here on a meteorite? No, such an event would create temperatures too high to sustain life even if there was life on Mars to be blasted to Earth.
Mars is and was too cold to provide a fit environment for the kind of life we see on Earth. What might have been living happily on Mars a few million years ago, if it was carried to Earth by aliens, would have found Earth too wet, warm, and inhospitable. What would martian life have eaten when it arrived here? What would it have breathed? Would the Earth's atmosphere provide the needed gasses in the correct amounts?
No, it is too far fetched for anything except a science fiction movie.
Earth is for Earthlings! Aliens stay away! hahaha Or I'll blast you with my ray gun! Or I will put a computer virus in your Mother Ship and destroy you all! (Evil laugh)... finale music begins... fading to black...

No, all life on Earth evolved on Earth. Mars probably did have life billions of years ago, but all that life died when Mars cooled down and lost its electromagnetic field.

The Earth was created from debris in outer space - life may have arrived from there as well - but not via Mars!

I believe men came from Mars, but women came from Venus.

Sorry my friend, I'm just trying to figure out how to keep life going on here. Stop dealing with the past, it's the future that matters now!

Of course, I thought everyone knew men are from Mars and women are from Venus. (Should that be the other way round?)

No, but then even if it did, the how the hell did it get to Mars? Jupiter?

no, after the big bang and earth was created, i believe that every thing evolved from bacteria
