“Everything” doesn’t mean equal amounts of every thing.
Yes, it does in this case. The universe is infinite.
Well that’s a completely bogus claim you’ve entirely made up and presented as fact. But I’ll bite anyways: even infinite sets can have different cardinalities. The set of natural vs real numbers, for instance.
(See how making claims with 0 support besides pseudo-ontological bologna isn’t helpful?)
You seem unable to separate faith from fact. And you could certainly use a dose of your “the map is not the territory” quip when it comes to your “logic”.
Whether or not this is true, it's somewhat irrelevant, as the observable universe is finite, meaning there's a finite amount of "stuff" that can causally influence us. What happens far beyond the observable universe is not worth dwelling on, as we will never see it or be otherwise influenced by it.
