There are no gods ... the very concept is incoherent. There are, rather, narratives that our brains create (or that are provided to us) which can seem very convincing, especially if the verification processes in our brains are turned off or bypassed--as happens during dreaming, with some drugs, in trance states, from social pressures and practices of some cults and churches, etc. And even our normal conscious verification processes can be fooled--overcome by illusions and "hallucinations", misperception, déjà vu, etc.

> I don’t know if everything happens for a reason

Another incoherent notion--events are locally caused, but there are no free-floating global "reasons". Aside from the sense of physical causation, reasons are intentions by intentional agents, e.g., we offer reasons for our beliefs and actions. Lacking an accurate metaphysical framework can apparently cause one to seek "God" via a tank of nitrous oxide that results in taking the narratives one's brain generates as being inherently veridical.
