Do you think that religion may be gone forever one day?

Hardly. Human psychology is a very complex thing, and from it derives the tendency to believe in things that don't exist. What can and does happen, is a shrinking of the interference of religion in physical matters. Millenia ago, humans believed that lightning was caused by gods. Now we know they're not. As time passes and science explains more and more about the physical world we live in, religion will gradually be relegated to dealing only with the moral and phylosophical matters.

Yes, I believe so. Someday all people will forget GOD, they will act like animals becuase they don't believe in GOD!

Very , very small possibility. People need imaginary friends and to feel special, to feel that there is someone looking for them, and cannot accept the possibility that this life is all we have. Also religions are wonderful ways of making money.

As long as there are people "pimping god" (whatever that god may be) and others willing to "buy" god there will always be religion.

I dont think so. I dont think there is a chance of that happening.

It depends on the role of religion. If religion's role is to fill up the gaps that science hasn't yet covered, then yes, it will go out of existance as science progresses. However, if there is a God, than the role of religion is not explaining events but creating a releationship between man and God, a role that science is not designed to fulfil. Many religions out there could be described more as philosophies (Buddhism) than faiths (which involve relating to a person eg Jesus, Muhammed etc...), so yes I think there will be fewer religions (as the philosophies get replaced by science) but those involving people will not die out.

I think this is one of those how do you define it questions. But in short: no. People will always want some kind of guideline or structure for their life. We might stop beleiving in dieties but we'll replace it with something else.
