I don’t think it was planned, but when humans appeared and had enough intelligence I think he decided to communicate.
So one day god was looking at the stuff he set into motion and noticed there was something intelligent. He then said, “Hi!” scared the creatures and thought, aww, they seem cute until they started killing each other.
As for my questions about the laws of physics you missed the point. It’s not how things work, it’s why it works that way.
