>>>The definition that I like, and maybe I can explain why, is that existence means having causal effect to the world (either directly or indirectly) - or, being caused by something that does. For example, a photon has causal effects to electrons since they couple together. Therefore, a photon exists. God could 'exist' if he created or somehow affected the creation of the universe since he would have causal connection with our universe. We don't necessarily limit ourselves to observables (e.g., physicalism), we merely say that in principle something that has causal effects or is caused by causal effects by something that has causal effects on our world has existence (regardless if we see these effects or not).
