@georgeob1,
Believing in lies is psychological { meaning normal} It is easy to see this natural phenomenon around the world. People believe in all kinds of Gods, religions, aliens, superstitions, so on and so on. certainly they can not all be correct.
We can talk about how others believe in things to be facts but yet you can see that they are obviously wrong when you have an understanding of the subject being discussed.
When it comes to our own beliefs we have confirmation biases standing in our way which makes us the same as those other people believing in lies.
If you truly would like to have different view points to challenge on this issue then at least listen to some of the professor's lectures on YouTube that teach these subjects then come to your own conclusion about the truth!
