Belief, Religion, and the Illusion of Knowledge

Lately, I've been familiar with three ideas. One is from the book God Delusion by Richard Dawkins. He argued that, maybe religion is a side effect of another evolutionary traits which enables us to maybe work as a team. Then Yuval Noah Harari introduced me to the knowledge illusion in his book 21 Lessons for the 21st Century, which enable us to believe to know something which we don't know personally but maybe known to someone somewhere. And in Denial of Death Ernest Becker explained that, Sigmund Freud did a great work on how people rather blindly follow people in a book (I have to read that). It is their urge to follow someone, to feel secure, like in the arms of their parents.

Now, I wonder, are they somehow connected in the depth of our biology? Is it some just different manifestation of same psychological condition? It can be. The blind belief that I know, or my God/Leader is right somehow looks emotionally similar to me.
