Many scientists believe there was because robots on the planet have found traces of water.
NASA has not discovered microbial fossils on Mars. NASA's Curiosity rover has not found any direct evidence of current or past life on Mars. The search for signs of past life on Mars continues with future missions like the Mars 2020 rover.
it did bilions of years ago but its all dried up now
Mars is believed to have formed about 4.6 billion years ago, around the same time as the rest of the solar system. It was formed from the same cloud of gas and dust that gave rise to the Sun and the other planets.
There is currently no scientific evidence to support the existence of past or present life on Mars. However, the possibility of microbial life existing at some point in the planet's history has not been ruled out, and ongoing missions continue to search for signs of past habitability.
Mars lost its water (or it all froze) fairly recently . . . about 1 million years ago.
Us - NO. But life MAY have originated there billions of years ago and migrated here - as bacteria.
about 4.5 billions years ago.
No, but there is fossil evidence to suggest that there was very simple forms of life (bacteria) on Mars many years ago when the planet still had an atmosphere and unfrozen water.
There is no evidence so far that life exists on Mars - or that it ever existed there. Of course, it may have existed - more research is required to be sure.
Sure. There could well be tiny organisms like bacteria or fungus on Mars. The chances of life on Mars increased when tiny outcrops of ice were found on photos several years ago.

None, there is no life on Mars at this time. However evidence that Mars once may have had flowing water in some areas, suggests that it might briefly have had life for a short period of time, a couple billion years ago before losing this water. However there is nothing that proves that Mars actually had life at any time.

There is currently no evidence to suggest that people lived on Mars in the past. Scientists are still exploring the possibility of past microbial life on Mars, but there is no known evidence of past human civilization on the planet.
