Because it took a lot of favorable conditions for Earth to have any life on it-- it would be almost impossible to have life here if not for being just this distance from the sun and having a large magnetic field to deflect the nastier parts of solar radiation.
And, for reasons still unclear, Earth has a lot of water compared to other planets, and it's mostly usefully liquid.
Compare to Mars: no decent magnetic field, so it's blasted by solar radiation, and what water there is, is frozen, which is hard for any life form to do anything with. Not a favorable planet. (But it's a second-best, next to Mercury and Venus!)
However, life in forms that we're not familiar with could well exist in parts of the atmospheres of Jupiter, Saturn etc, and some of their (many many) moons. Maybe those environments are actually better for life than here on our big wet rock.
