Is Christianity based on older myths?

It is funny you skipped verse 18: Galatians 1:18 Then after three years, I went up to Jerusalem to get acquainted with Cephas and stayed with him fifteen days.

Cephas is Peter.

Galatians 1 is a chronological series of events Paul is relaying. In Gal 2:9 he talks about meeting Peter and John at another time.

I intentionally omitted 18, which is obvious; for reasons we'll get to in a moment. You pointed it out to bolster your view that Paul developed his gospel from interviews with those that walked with Jesus. Game, set and match.

I quoted Paul saying that his gospel did not come from humans, but from revelation; Paul's words in Galatians 1:12. If you claim that the Cephas in Galatians 1:18 is the apostle Peter insinuating that this is where Paul received his gospel; well then, you have caught Paul lying! How can this be when your argument hinges on the assumption that there is no reason for Paul to lie?

Later Paul tells us that he is having a conflict with Cephas in Antioch. I remember what Paul's solution was, do you? That's right, Paul hauled ass to Jerusalem to discuss the situation with Peter. Pray tell us, why would Paul travel all the way to Jerusalem to discuss with Peter the problems he was having in Antioch with Cephas if Peter and Cephas were the same person? Boggles the mind.
