So how did Paul know that Jesus appeared to 500 people at one time?
It’s not in any Gospel — it is Holy Tradition — he was told this person to person.
Presumption on your part....and a bit of a stretch to call it "tradition".
Could have been Luke, could have been the Holy Spirit, could have been Jesus.
There is no conflict here. The Gospels were written after Paul was executed.

There’s no new doctrines in a testamony like that. Jesus Christ clarified what kind of ‘great fish’ swallowed Jonah: a whale. That didn’t change the story.
