The power of religion has hardly diminished in last 10000 years. The assumption that with progress of knowledge about creation and the natural world, our faith on an unknown God will diminish does not seem to be correct. Even well educated scientists believe in God.
I think our insecurity and inadequacy is too strong to be dispelled by reason and data alone. At least in it's present form.
I think instead of trying to explain away the Cosmos and the creation, study of our brain will yield better result in dispelling religion.
Draft post. I will work on it later.
