Other than the bible and people telling me I need to have faith to believe in a god...this God concept has never confirmed or denied this itself.
So really, what we would have to put faith in is what the bible (a book) says, and what people say about what they feel is true. And that's ALL we have. There is no more evidence than that to support any other god belief either. Mankind has created thousands of gods, most of which, the vast majority of people no longer believe in. But at the time people had faith in these gods too.
Even if I wanted to believe in and have faith in what people say about their gods. How would I choose which god to put my faith in? None of the gods that people have faith in confirm their reality, in fact without this faith the god ceases to exist at all (a christian god does not exist to a hindu, and the hindu gods do not exist to christians). It's all hear say and second hand information.
Some non atheists will tell you not to listen to them but to listen to god...well I've never 'heard' from him. Then it becomes a matter of HOW to hear from god or more faith. But exactly how much faith is needed? I used to have faith coming out my eyeballs...never 'heard' from any of the gods. Maybe I had the wrong god. Maybe I asked the wrong way, maybe I didn't have enough faith, though god knows (if he was real) that I did. Would a god be so picky that if you asked questions the wrong way he wouldn't speak to you?
But non atheists all swear by their chosen god and tell you to have faith no matter who their god is. Vishnu, Krisna, Jehovah, Zeus, Jesus (if you're a trinitarian)...etc.
Now either most of the world is lying about thier chosen gods. Which must be the case if only one is real (monotheistic belief). Or they are kidding themselves. I prefer the second option because I don't like to think that everyone lies. I know I didn't when I believed.
