I'm all too familiar with this quip. Are you saying 1) that you have no theism or 2) that I do?
I've seen nothing that proves there is a god or higher power.
I've seen nothing the precludes a god or higher power.
There is zero evidence to support OR REFUTE the idea of a god or power greater than man.
In all fairness and out of respect, I will advise you that wandering down this flawed line of reasoning will not serve you well. I fully realize that the quip you made is very popular amongst Christians; however, they never had the benefit of having me explain how they are shooting themselves in the foot with it.
Theists: You must believe in our god - though we have no evidence, and obey the rulers of our faith
Atheists: You must believe there is no god - though we have no evidence, and obey the rulers of our faith
Agnostic: Believe what you want, your faith is your own business.
