Maybe we're being a bit hard on him on reflection. It's fine to challenge yourself by exploring ideas that have yet to find general acceptance. There's been some research, there's some literature and there have been speculative links made between consciousness outside the body in the universe at large that transcends the human body's puny lifespan. What we have may be not all there is and you don't need God for it. The challenge to the intellect is considerable, though a lot of the stuff plumbs the murky depths of popular science. Just a couple of things about it all, though. First, we need evidence. Not anecdotes, not witness (which, unfortunately, is what stuff like near-death experiences can only be until we have a ton more corroboration than we have now). A pile of St Bernadettes won't cut it. And linking speculative notions to other speculative notions, such as multiverses and expanding foam universes, simply multiplies the chances of going USCWAP*. it's a damn sight more likely to have truth in it than God, because the speculation at least doesn't defy the intellect by requiring magic and the quantum physics connection is not implausible. Of course, there are ways and ways of presenting it. Another thing is the all-trumping enticement of the afterlife, or whatever you might want to call the non-death of consciousness. That can make you believe stuff that maybe you ought to be questioning a bit more.

In the meantime I prefer to fight for my personal enlightenment in ways other than quasi-druggy mind alteration!
