Question for christians?

Why do you fervently defend your faith When there is no evidence of god or anything about your religion actually being true except for the good book itself and then when confronted by someone of a religion such as following the old gods such as Thor and Odin you look at them as though they are confused and there religion is clearly false what is with the double standard might i ask please don't block me because i know a lot of you would just love to but i really wan't to get an answer. P.S. im not trollin relax.
