Individual Hind also saw visions of Lord Krishna.
Religious people tell white lies all the time if it helps people come to the faith. If he was telling the truth, then he fell and had a hallucination of a light. He decided it was Jesus. He claimed it spoke? He was excited and heard voices then. The story is a huge myth. Paul seeing a vision does not make a myth real.
If someone sees Harry Potter tomorrow does that mean Harry Potter is real or they just had a vision.
Your excuse "Paul had no reason to lie" is ridiculous. He may be telling the truth and had a hallucination. But he likely wanted to bring new followers and would not have thought of it as a lie. It doesn't make a make-believe savior demigod real? The story is fake?
Those Hindus weren't persecuted and jailed and they didn't go on missionary trips. Why would Paul want to bring new followers into Christianity? He persecuted Christians. He had nothing to gain joining a persecuted group of people. He was jailed and persecuted after he believed in Jesus.
