No, there are not *all* natural numbers in any healthy mathematical theory. Have you read hundreds of posts without learning that basic stuff? > > There is no difference between "actual" and potential > infinity as long as we restrict things to > findable quantities.
If you are incapable of learning what potential infinity means, as it is suggested by your statements above, then your assertion is understandable but nevertheless wrong.
Actual infinity requires that *all* natural numbers are in the list but not in a single line. That is a contradiction. Since they are, in fact, not in a single line (since there is no last findable line), only the other alternative can be wrong: The existence of all natural numbers.
