Hmm. i think you need a universe at least 10bn+ years for intelligent life as you need to have had cycle of earlier stars going supernovae to create the heavier elements.
That aside, 13bn years old is young. literally an instantaneous flash in the context of all time until heat death of the universe.
You see red dots/monsters on hubble or JWT.
Those are the ones fundamentally shifting theories about how early stars/blackholes/galaxies can form. (there are other factors like dark matters that can play a role but nobody knows for sure yet)
13bn years is not too young with that context in mind.

That alone is sus, because if we have infinity billion trillion years until the end, and we're so close to the beginning as to be a rounding error, it's weird.
