NASA scientists believe that it is technologically possible at the present time to create considerable global climate changes, allowing humans to live on Mars. But this will not be by any means an easy task. Raising the atmospheric pressure and surface temperature alone could be achieved in a few decades.

Mars was in the habitable zone and I would stake a claim and there was life on it at some point.
We are made from the stars and if we existed here, then we probably existed on Mars first, speculation of course

Rounded Pebbles On MARS Reveal Past Flowing Water
(visit the link for the full news article)
LOS ANGELES (AP) — A fresh analysis by NASA's Curiosity rover confirms a stream once ran through Gale Crater on Mars.
During a pit stop last year, Curiosity came upon hundreds of smooth, round pebbles that look strikingly similar to deposits in river banks on Earth.
Scientists believe the rover rolled onto an ancient streambed, but needed to study the stones in more detail. So Curiosity snapped high-resolution pictures and fired its laser at several pebbles to analyze the chemical makeup.

While i do believe that there once was water on mars I do not think that this is in any way shape or from proof of it.
NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here. This geological feature on Mars is exposed bedrock made up of smaller fragments cemented together, what geologists call a sedimentary conglomerate.
"This tells a slam-dunk story that water flowed through underground fractures in the rock," said Steve Squyres, Cornell's Goldwin Smith Professor of Astronomy and principal scientific investigator for Opportunity. "This stuff is a fairly pure chemical deposit that formed in place right where we see it. That can't be said for other gypsum seen on Mars or for other water-related minerals Opportunity has found. It's not uncommon on Earth, but on Mars, it's the kind of thing that makes geologists jump out of their chairs."
