Again, I don't think our language dictates reality, the other way around, but this might be helpful. Which definition of infinite are we talking about here:
Etymology: Middle English infinit,
from Anglo-French or Latin; Anglo-French, from Latin infinitus,
Date: 14th century
extending indefinitely : endless
immeasurably or inconceivably great or extensive : inexhaustible
subject to no limitation or external determination
4 a :
extending beyond, lying beyond, or being greater than any preassigned finite value however large <infinite number of positive numbers> b :
extending to infinity <infinite plane surface> c :
characterized by an infinite number of elements or terms <an infinite set> <an infinite series>
1. The number of objects cannot be endless at any given point. It can continue to grow indefinitely, but it can't "be" endless, because it would have to have an end at which it "be" endless. Nonsense.
2. The number of objects cannot be immeasurable, because a number is a measure.
3. The number of objects can't have no limit as a number is a limit.
4a. It is always greater than a number, never equal to a number, so it can't be a number.
4b. It never reaches infinity, it extends "to" infinity.
4c. This is the only infinity I say actually "exists" in nature because its a relationship, not a number.
And, in a sense, by saying that infinite doesn't mean everything, that implies that everything isn't infinte, which is the point I'm making in the first place.
