It’s not so much that I believe it ‘by default’. Rather, when I’ve examined the historical case for the resurrection, the arguments that it really happened seem stronger than the arguments that it was a hoax, or a mass hallucination, or that he fainted etc.
I’m sorry if this comes off as rude or blunt, but here goes:
I am not aware of any evidence that resurrection is possible, or indeed that anything that could be called “supernatural” is real. Don’t you need to establish that before you can claim that arguments for a flipping resurrection seem strong? What am I missing here?
