This Flat Earth Deception post features an explanation for why people see the moon upside down from each other.
On the Flat Earthers in Christ Facebook group, someone posted this meme about how people in the Northern Hemisphere and Southern Hemisphere see the moon inverted from each others.
Sadly, the comments on the post show that flat earthers blindly accept that explanation.
But the fatal flaw is that on the flat earth model, people in the Northern and Southern hemispheres cannot see the same side of the moon, but they would see different sides of the moon.
But we can prove that people in the Northern Hemisphere and Southern Hemisphere do see the same side of the moon, because they have the same basic angle of perspective to the distant moon.
It just appears upside down to people in the Southern hemisphere, because of their perspective.
Once again, a supposed explanation to prove the flat earth actually shows the flaw with the flat earth theory. And once again, the people in that Facebook group have no discernment to see the truth.
