Earths diameter is 4x bigger than the moon

Since it’s equal distance from us as we are from it, the Earth would look 4x bigger in the moons sky as the moon looks in our sky

Since we know what lens was used and approximately where the photo was taken we could do the math to prove it one way or the other

Or, if I were to take a 60mm photo of the moon from earth, then enlarge the moon 4x, it should have the same approximate size as this photo, which it does

We spent billions,
Billions going to the moon or
Billions faking that we did

If we faked it, we didn’t make a silly mistake like getting the size of the moon wrong
