This one is easy. That is because I do not believe in god. I don't feel like there is no way of knowing nor am I unsure in any way. Why? Well, the reason people believe in god is a book that is not even a good book and has none of the features of a nonfiction book. It reeks of folklore and other types of fiction, such as outright bullshit. Therefore, I do not believe in god.
If I were to be agnostic, I would have to believe anything is possible and that leaves me in an awkward position.
