How might I show my father God does not exist?

I don't believe, but all I know is that god has never contacted anyone, the bible translated inaccurately to fit the appeal of king James, the earth is very old and the bible is wrong about times, the horrors inside of it and evolution is almost entirely fact with key examples. What else might there be that does not exist? I don't not want to be rude, I simply want to show him. EDIT: My father believes in Christianity, I don't know if this belongs in ask reddit, but it's more on atheism.
