Not current life. Signs of life in the past. There are indications that Mars had free-flowing water at some time in the distant past. If there was free-flowing water, then it may have been warm enough and wet enough for life to have evolved (if only bacterial life).

Its as good as any other place, we think Venus and Mecury are too hot and have deadly gases so we look to Mars. Which is probably a waste of time. I love the Star Trek series but that is all science fiction. Just because we can dream does not make it happen all the time.

There were two really.
First, it was reported that a meteorite from Mars possibly contained fossilised life forms - see link 1.
Secondly, the possibility that Mars actually has quite an amount of water (albeit frozen) - see link 2.

Ice caps indicating water. Mean temperatures are not as extreme as other inner planets. Some features show evidence of (geologically) recent water flow.

When a space craft came back from mars, there were shocking pictures of water. Since depends on water, this might mean there is life on mars.

sufficient solar radiation
an atmosphere
evidence that at least at one time there was water
near by (making exploration easier than, say, some planet circling Alpha Centauri)

Because it is round.
