Think about what it means for the moon to be visible in the sky...that side of the planet has to face the moon. Which means the planet has to take the same time to spin around once as the moon takes to travel around the planet once. Otherwise that side of the planet would get ahead of the moon or get left behind it.

I think I'm missing some vital piece of information in my brain because in my wee brain, I am talking moon is always above my head all the time, it does moon stuff, maybe it rotates like a good boy, but it's always there while the planet does it's rotation around the sun and does it's daily rotation. In my mind, the moon and earth are holding hands while the earth does it's 24 hours a day, 365 a year.

So I am really missing some kind of epiphany in understanding.
