I'll add to Brendan Ward's explanation that there is a wobble in the moon's rotation that allows us to see a tiny fraction more of the moon than just the full face that is always pointing towards the Earth.

Fraser Cain explained it perfectly.... nothing to see here folks.

Very good. You sound like Timothy Elyphont (Justified!)

Until millions of people can go up and see earth and the moon for themselves, Nasa and their minions are all evil lying scum. I can't wait for the day the truth comes out and these scum get what they deserve. I'm so sick of these scum thinking they got away with it. As soon as we raid their underground bunkers the sooner we get the truth.

Brendan Ward knows what he is talking about!!!! The flat earther never investigates the truth. He is trapped in his mind.

Yes, it makes perfect sense. The moon rotates on its axis in 27.32 days. It also revolves around the Earth in 27.32 days. Therefore, it always presents the same face to the Earth. Its equatorial circumference is about 11,000 km. It equatorial rotational speed is about 17 km per hour. So it takes about 11,000/17 = 647 hours to rotate. 647/24 = about 27 days. What is so difficult about this?

Stupid shit. Maybe because that's the same rate as it's orbit around the Earth. Can you say "tidally locked"? I didn't think so.
