Many scientists believe there was because robots on the planet have found traces of water.

nope, the oil that was made here on earth comes from organisms that died millions of years ago. from what we know, there hasn't been too much life on mars.
There have not been any such discoveries on Mars.
Actually I believe that the asteroid belt between mars and Jupiter was Mar's sister planet. However it was destroyed somehow hundreds of millions of years ago and could have possibly stripped Mars of it's life giving atmosphere.

Us - NO. But life MAY have originated there billions of years ago and migrated here - as bacteria.
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.
about 4.5 billions years ago.
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.

It does not have coal on it but it used to thousands of years ago.
