It will, religion is not based on a few unknowns, it is not logical, religion is something people are indoctrinated into as kids, it's an excuse for harming others, it is an easy solution to answering any question about the universe, it is oversimplification of reality, it is a way to control others and to give hope to the believers in some cases. Religion may change, but the core that has plagued humanity for thousands of years will stay here for a very long time after it has become unreasonable to believe in their deity.
