>How can all of humanity be present in Adam?
He's literally the first physical man, how can we not?
>Also, wouldn't such a belief imply the pre-existence of souls?
No, but it does mean anyone of the line of Adam (the first man) inherits Original Sin, a corrupted will from birth that we can be forgiven and washed of in baptism.

>but that view of original sin is just common catholic mind games
How? It's a logical proposition, we're all literally sons of Adam in the flesh. We have to be re-baptized to be re-born in the spirit of Christ.
>that once we reach an age where we can sin willingly on our own rational self, we invariably do.
"invariably" is a misnomer, you then argue that there are souls that have never sinned, and that is not 1:1 with the scriptures.
