> It is worth to mention that all living beings in earth are descendants of same cell. Even in earth there is no sign of multiple different cell formation which shows how lucky we were.

I don't see why this has to be the case. If unlikely conditions are correct for something unlikely to occur, then it's not longer unlikely to occur multiple times.

E.g. if you play around with chemical reactions and you hit the right conditions, it usually happens all over the place, and not just one molecule combining.
