I dont't think religion won't ever end.
I just hope monotheistic ones will end soon.
If you think ONE God exists, you can identify with it, therefore you can incidentally guess you're superior to something else.
If, on the contrary, you believe in Gods (think of Roman and Greek ones, or other animistic religions) you can identify yourself with one of them. And no Gods is superior to any other god. They all have their own pros and cons.

What do you think?
