Earlier quoted context omitted.
He revealed himself to them and only them, ignoring the rest of humanity all over the globe. In all the universe he chose just earth for his people, and over all of earth, he just chose a tiny section to reveal himself to. Omniscient and omnipotent but a very human scale for his messaging.
Who said he ignored the rest of humanity? That's not what the record shows. Most people know about God. Who said that in all the universe he chose just earth? You're assuming too much about the motivations. I do not see what the issue is with a "very human scale" for messaging. That's...how you communicate with humans.
Right. Why would the omnipotent creator of the universe communicate the same way I do?
