That both the Hindu model and the Christian model exist with the same “evidence”, that of their respective scriptures, must be evidence by counter-example that scripture is not a valid source of evidence. If all scripture is valid then they can’t both be right.

Each seems internally consistent to its followers and each produces that feeling of rightness/joy/epiphany. Each also has its share of good things, loving others, helping others, being a generally decent person that is sometimes used to defend scripture. “If Jesus/Krishna was right about that then he must be right about the rest”.

Anyone looking a Hinduism and saying “can’t be right – flying monkey armies” should note that “virgin birth and resurrection” is also very counter-intuitive. Both sides can argue that this is just allegory and not important, something more likely from the Hindu side I think.
