It's difficult to discuss with people that don't have scientific background...
I agree. When someone has an ideology or a religion to defend, rationality stops
Absolutely good points. When people believe in science theory, especially theory that can't defend itself in the face of stringent analysis - like evolution theory - they have a religion going for themselves. The religion of evolution.

''Believe in science theory'' Why do you need to believe in it? You can study it and see it for yourself that is real unlike religion, no matter how much you study it you will never find evidence for the existence of gods.
