First of all: What do you mean by faith and religion?
I like the ancient world where there was a different understanding of religion than it is now prevalent with abrahamic religions. There was public religious services and private practice of philosophy to deal with moral questions and so on. In my opinion, having a one-stop-shop like Islam or Christianity is dumb.
Supernatural beliefs should be replaced by science and an actual understanding of the world.
Moral convictions and purpose in life can be achieved through philosophy and held as sacred as supernaturally-inspired beliefs can.
Then there is a host of other stuff like community, rituals, etc. But it really depends on what is important to you, OP.
