Is the hypothesis that antimatter is moving backwards in time compatible with the hypothesis of annihilation of matter and antimatter after the big bang?

It is said that the big bang should have produced equal amounts of matter and antimatter. Matter and antimatter annihilated (at the exception of a small part of matter) so that there seems to be not much antimatter in today’s universe.

Is the above-mentioned hypothesis compatible with these assumptions? It seems that it is not compatible: if we would presume that matter and antimatter have different time directions. would this mean that the matter and the antimatter generated by the big bang never met (??) so that there was -timely- no possibility for annihilation?

Is the above-mentioned hypothesis compatible with these assumptions? It seems that it is not compatible: if we would presume that matter and antimatter have different time directions, would not be the consequence that the matter and the antimatter generated by the big bang never met each other (??) so that there was -timely- no possibility for annihilation?

Is the CPT theorem compatible with the hypothesis of annihilation of matter and antimatter after the big bang?

It is said that the big bang should have produced equal amounts of matter and antimatter. Matter and antimatter annihilated (at the exception of a small part of matter) so that there seems to be not much antimatter in today’s universe.

Is the CPT theorem compatible with these assumptions? It seems that it is not compatible: The CPT theorem says that matter and antimatter have different time directions. Does this mean that the matter and the antimatter generated by the big bang never met (??) so that there was -timely- no possibility for annihilation?
