how am i close minded when i consider all the evidence?
Consider this: I do not know if the tooth fairy is real and i cannot prove it either way. But i am a tooth-fairy atheist.
The meaning is that it is ok to not believe in something that has no evidence to support it. It is perfectly logical. I suggest you read about the "orbiting teacup" writting by the philosopher bertrand russell since it explains this better than i can.
