Will we ever find Life on other Planets???

Primitive forms should be quite common in the universe and we'll likely find some in the near future, but don't expect to find intelligent ones easily. Had Mars had larger mass and so kept its atmosphere denser through time, we could still find life on it (or more life if some rare remnants are still left and lurk somewhere).

There is a theory that says that life appeared on the seas of Mars and, when it evaporated by the Sun life was kept in that steam of water that went out of the planet, got frozen and eventually ended colliding with the Earth. So our life may be Mars' life. We could be aliens!

Not impossible, but the higher solar energy and denser atmosphere available on Earth make it more likely that life started first and evolved faster here than on Mars. But exchange of early life forms cast in space between the two planets isn't impossible, it could have happened, due to meteorites fallen in the seas, for example.
