I know of no reason to insist that only people have an afterlife, and that other creatures do not.

I know of no reason to insist that people and animals do NOT have an afterlife either...other than blind prejudice based on nothing at all except a sweeping assumption that one already knows. And no one here does.

It is not "blind prejudice" to insist (wrong word but let's go with it for now) that there is no afterlife. It is very sensible, for a start, to suspect that the concept of afterlife has survived almost solely because it is a convenient instrument of control for religions. Whether jam tomorrow, or don't dare step out of line, it comes in handy. One might even surmise that religion actually relies on the concept for its very existence, so neutrality there then! There's also the argument that the idea of an afterlife panders to the ultimate conceit of humanity, that we're so special that this can't be all there is. Of course, none of this means that there is no afterlife, but I'm afraid what it does mean is that afterlife is on the same footing as God's proposed existence. So I want evidence. I'm not insisting there isn't one. But I want to see the foundation on which the concept is built. Again, not only is there no evidence for an afterlife but the concept of a soul, spirit, whatever, carrying on after the physical body dies runs counter to the laws of physics. Calling afterlife sceptics/deniers blindly prejudiced is actually a pretty crude and unintelligent tactic. It isn't us who need to do the explanatory heavy lifting on this one, is it?
