Even theists woudn’t believe it. If I told some believer “I am god” they’d take it as a joke, but what if i actually was? What if I’m a reincarnate or some shit they talk about in religious books or whatever?
I think you misread, it says “I’ve found god” (as in, “I’ve suddenly decided I both believe in god and believe I have a close personal relationship with god”), not “I am god”.
