How exactly extraterretial life is a statistical fact?

How is it not? Other than extremely anthropocentrically?

There are at least 200 billion trillion stars in the universe that we are aware of. That is a number beyond our comprehension. Stars generate elements. Elements form molecules. Life is built on some of these molecules.

  • The statistical argument is basically:

    Multiplying a number beyond our comprehension by an unknown probability >= 2

    Right?

    • I would say the statistical argument is the null argument. To invalidate it you should instead need to come up with a reason why in a billion trillion structurally relevant constructions we must be the only one where life emerges.
