The problem here is not that you are being rude or that you are unteachable.
The problem has nothing to do with you as an individual.
We've just been burned too many times before.
If you have honest questions and are willing to approach the answers with an open mind, hurray!
But, too often we run into the exact same arguments, usually a version of one of the following -
"Your evidence is not real, and despite the fact that I know nothing about that field (genetics, geology, particle physics, etc) I discount your data out of hand."
"Nothing you tell me will overcome my devotion to what I hold to be true (Bible, Koran, Etc)"
"Though you have provided me with logical examples which demonstrate exactly what I'm asking, I still discount your evidence by simply restating my possition unchanged".
If you can avoid those three statements, you'll find a lot of information and helpful teachers.
