1. What happens in an imaginative brain is not evidence of an afterlife.
2. The thought of an afterlife certainly has appeal as a fantasy, but that is not evidence that it exists. 3 Whether Darwin was right or wrong has nothing to do with it.
3. The alleged resurrection of Jesus has no good evidence. That gods get resurrected was already a part of myths at the time of Jesus. You probably don't believe in those other myths.
4. "Near-death" is just that. The brain is in bad shape then. But the interesting thing is that NDE's vary by religion, with each religion having images of their own religious figures and legendary afterlives. I doubt that you are going to switch religions because of that.
5. Science doesn't pretend to know everything. Science is just a methodology that helps determine truth. But it only can deal with testable things, and heaven is beyond that.
