Atheists: What would you consider credible communication from God?

[Trailblazer]

Its odd that god would be trying to convince one person as opposed to just proving to everyone at once that god is a thing.

God does not want to prove Himself to us. He wants us to prove He exists to ourselves.

I'm not sure but if god was the ruler of all men and women then they would already know.

Why would they know?

They wouldn't be relying on one dude that hears the voice of god as god could speak with everyone whenever and however in whatever form it takes.

God could speak with everyone if He wanted to but since He didn't we know He didn't want to.
Rather, God relied upon the dude that heard His Voice.
