Personal experience does NOT count as empirical evidence. Nobody on this forum has yet demonstrated any kind of evidence that supports the existence of a supreme being.
bazillion: "If that's not good enough for you, I suggest that you pray. Do that and you'll get the message, sooner or later."
That voice your hear inside your head when you pray... that's called YOU. If you sincerely believe you are receiving messages from a supreme being, then well, you have some traits in common with people who have mental illnesses.

Therefore, science could eventually unlock all knowledge and all the mysteries of a corporeal universe that follows physical laws. The part of religion that delves into Ultimate Reality, however, can never be known from this side of existence. We can touch Ultimate Reality or God, but since it is beyond experience, as we know it, we can never speak about God because God would never register in our minds other than vague, ephemeral images. "
The very search that you recommended just refuted your other point about receiving communications from God! How ironic.
Also, these are questions that science has not answered YET, and that is no justification to believe in invisible, intelligent beings.
