Can't we calculate the rough possibility of the beginning of life by saying: It needs at least 80 atoms to make a thing that can reproduce itself? So on billions of planets with each hundreds of millions of square kilometres it would take x billion years to just by accident combine those 80 atoms.

@Jm-wt1fs But we can calculate that I think, and it would be under a billion years on multiple planets, and that is the point of my post :) Of cause there may be other means of life to start that may be much faster, but at least a combination of 80 atoms just by accident should be a lower bound to the beginning of life. And that 80 atoms could form e.g. out of biomolecules or hydrocarbons of about 10 to 16 atoms which are abundant everywhere, thus needing only 5 to 8 parts to combine. Of cause this combination must be meaningful in a way that it can reproduce itself, but if we have quadrillions of tries (and we have that even on one planet), that should be possible. Maybe those 80 atoms are formed in a disc in a way that other suited biomolecules can attach to easier than non suitable ones, to form the same disc again and again. Then after time, some discs break apart and thus both parts start over. So we have the simplest form of life possible that most scientists wouldn't even call life being much simpler than even viruses. Then we only need evolution, which is inherent to every reproduction and we end up having meaningful life.
