It does seem like a pretty strange coincidence that the moon would rotate at exactly the same rate that it revolves around the Earth.
But of course it’s no coincidence at all.
When the moon was much closer to the Earth than it is now, the Earth’s gravity distorted the moon slightly, so that it’s somewhat egg shaped.
As a result, the pull on the moon is now slightly stronger on the pointy end, keeping it always faced toward us.
