Reply to comment by FellowConspirator in Do we have any compounds or materials on Earth that compared to the rest of the universe is incredibly rare? by SwordArtOnlineIsGood

Yeah... extremely specific biomolecules (such as u/FellowConspirator's DNA) are likely to be present only on Earth and nowhere else.

That is not how it works. You can have an infinite number of events, out of which each event repeats only finitely many times.

Example: There are infinitely many natural numbers. Only one of them is equal to 2.

No, that does not follow. Consider that rational fractions like 1/7 have infinite decimal expansions but only a very small number of patterns occur. Even for irrational numbers with non-repeating expansions like pi or sqrt (2) we can't be certain that every pattern occurs.
