1. Not a flashback, he was in some weird coma induced mental episode due to the electric shock from the cable box.

2. Not a paradox at all, this is the only case where he literally Time Travels, he freezes himself for 500 years and wakes up in the future. His actions in the future cause a split in timelines, which is eventually corrected and he is sent back in time by the future athiests.

3. Not an animation error, the word you were looking for was “Editing”, it was an editing error.

4. Whilst it is a plot point that only serves that story arc specifically, it’s still true nevertheless, he does in fact time travel to the past.
