There is a woman named Sally who believes in magic-talking but invisible leprechauns who live in the sky who will let her live forever if she follows the rules that she believes they told her, she has no proof of their existence whatsoever except for a book she claims that is their word, she is illogical and feels since you can't prove it, it could be true. Theists may not believe in leprechauns but they believe in their religious superstition blindly. They feel the same as Sally, Theists can't prove God is real and will say you can't disprove God so he 'could' exist. We unfortunately, in the state of existence we are, can't prove or disprove God but the existence of Gods [or the Biblical God and others of organized religion] is just as likely to exist as Sally's leprechauns, which is so EXTREMELY improbable that it is best to refuse to believe in any silly unproven superstition such as deities and to move on with our lives as rational, sapient, delusional, mentally-healthy homo sapiens.
