If you want to solve something with statistics, solve something that's determinable.
Tackling your problem, start with the known facts, and a bit of logic:
* Every physical object in the universe is composed of atoms, and an atom of hydrogen here on earth is just like an atom of hydrogen in any star in the universe.
* The very act of being a star brings about changes whereby the star is eventually reduced to heavier elements, mostly iron.
* Solar systems are created when enough matter condenses to form a star and satellites.
With these facts established, we extrapolate that the the life-cycle of solar systems are similar. They form, are comprised of the same elements, and fade toward the same end.
The two major variables are the balance (proportions) of the elements, and temperature.
Are we unique in the universe? Absolutely. But only in the sense that life evolves. The life on this planet today is unique with respect to any other day. Different people, difference plants, different animals, different species, etc...
When the elements blend with the right balance and a suitable temperature, there will be life.
