That's a great comment. I think even if miracles happened more often, I would also need some other evidence to address the usual atheist arguments.

For example, we already know what happens to your memories when you die, because we know that memory formation happens in the brain (MRI scans) and the brain decomposes after death. If that story is wrong and there is an afterlife, I'd really like to know the details. Even if I could reliably cause lightning by praying to Thor, I'd still be curious about that. And about the lightning.
