Cogito Ergo Sum
In the set of all possible Universes, ONLY in those that have matter is it possible to have observers who notice that there IS actually something. These need not be Humans. That is anthropocentric.
Nonetheless, in order for us to notice that there ios a Universe, that Universe must be imbalanced between matter and anti-matter.
Either there have been a large number of Universes in different times and places (different and probably non-connectable dimensions), or the one Universe has repeatedly cycled until it ¨got lucky¨ or it just got lucky first time.
(OR, there is some underlying rule of physics and matter that we don know about , yet)
