Why no religion? - A doubt raised

In the conference Beyond Belief, of the first five speakers all spoke to the fact that religion impedes progress in the world, especially that of science. Three of the five said that we must fight to get rid of science in the world, the other two agreed but said it will probably always be here, and one of those two stated that there is no reason to fight against them, just prove by action. I personally do not think that there is any reason religion needs to be stopped, not do I think that it ever will be. I know that evolution basically says that it will be, because those who depend on religion are the weak, therefore the strong will advance and survive and the religious will not. With that being said, shouldn't evolutionist believe that it will just go away with time inevitably? If not, does this alone not debunk the ideology of survival of the fittest? I do not know, I only ask.

But religion has proven that it has added more to sciences past than any other. The Muslims between the 9th and 12th centuries, Christianity and Judaism the last couple thousands of years. Apart from the scientific aspect, because that is not the only important aspect in life, religion has served to do much more. Likewise it has had its negative effects, but does not survival of the fittest, euthanasia, and Hiroshima also have the same. There are things that science cannot fulfill. As Laurence Krause stated at the end of session 2, "If science proves that being delusional causes us to be happy, will we say stop being delusional?" Or if science leads us to no longer desire life, will we choose science or life? Darwin himself stated how he missed being able to simply enjoy something without having to try to understand everything. And Dr. Weinberg noted our intrinsic desire to be with others in community (that of its root of having something in common). If we discover that it is necessary to being happy, but likewise impedes our progress in science, economy, humanity, etc. will we rid ourselves of happiness, joy, excitement, etc. for the prior?

Can we even answer these questions yet? I think I am turning skeptic and I don't like it very much because it doesn't lead me anywhere ahead, just in circles.
