It's possible. Many scientists speculate that comets spread organic materials throughout our system, and in places where the conditions were right, life arose.
Earth could have been one of those places. I'm thinking Mars probably was too. Unfortunately for Mars, things went sour for some reason.
I'm no expert, but I think it might be that Mars' mass wasn't enough to keep an active core alive to maintain an effective magnetosphere, and then the solar winds beat Mars up.
I also believe it's very possible that life is still there in some nook or cranny, or underground. Somewhere that's protected from radiation.
I hope I'm right and we find it soon.
