Did anyone ever notice this?

When you question the beliefs of those who put their faith in macro-evolution, abiogenesis, the big bang theory or any other theory trying to explain the origin of the universe & life they say "You just do not understand!" "You are stupid!" "You just deny facts!" Is it really because they are so superior in their intellect or is it something else? I highly doubt they fully understand the theories they believe. New theories will always be made with no real proof. And they will be defended by those who chose to not believe in the Lord Jesus Christ. I believe that is where the problem lies. What do you think?
