Incorrect; the majority of the hydrogen and most of the helium was created
in the first three minutes, but that is irrelevant to the discussion.

Hydrogen atoms were created in the big bang. Have you got some other
source of hydrogen?

Free neutron decay.

Ergo, the statements "Every atom of hydrogen was created by the Big Bang.
None since." are obviously false.

You might make a case that all the quarks were created by the Big Bang
and none since, but that is not what you originally said.
