“The point is they didn’t...”
Well, they clearly did, we have the pictures.
“or you have to explain why the earth appears so small when clearly it is many times larger than the moon”
I’m really not sure what you are expecting. There are obviously no photos where you can see the apparent size of both the earth and the moon side by side even though the photos need to be taken from two completely different locations. So the only way we can actually make that kind of comparison is if we had two photographs, knew the exact conditions that each photo was taken, and we had some landmarks in the photograph that we could use to get a sense of perspective. We’d also probably need to know the technical details of the cameras that took the photos and how they were configured with lenses, zoom, etc, since those things could have an effect too. Sorry, but I’m not really about to devote the kind of time and effort to do all that because some random person on the internet wants to be a contrarian.
I am expecting the apparent size of the earth as viewed from the moon to appear somewhat larger that the moon appears from earth considering that the earth is 4 time larger than the moon.
