Let us think about it. There's a lot of scientist and inventors that are religious. There is Catholic and Muslims. They are not stupid people.
Nobody is saying otherwise, so why bring up this point? It has nothing to do with what you quoted.
What do you think will happen if there is no religion in this world ? The world will be destroyed !

What happen if there is no moral and rules ?
Morality would't disappear anywhere with religions gone - hell, only a very tiny fraction of religious fundamentalists follow their own religion to a tee. Doesn't take a smart person to see that as such morality is entirely subjective thing, not bound by any religion.
There will always be a war.
Sure will, either because of religious differences of because of pure greed, which in many cases uses religion to justify its actions. We agree on this point.
I cannot imagine a world without God, a life without purpose.

You're mixing up so many things here it's not even funny anymore. Yes, many (most?) religions include parts of peace, love and happiness. Generally they follow after those parts which are led by the sword. And right, not all muslims are bad; some of them just actually follow their holy book, while others watch by and allow that to happen.
