Apologies to Dean Martin (unless he was a tare too).
For now, I have only redacted this post, that I stole from another topic.
The flat-earth tards claim the moon is a flat disk which emits its own light. Few claims are more stupid than that one. I would rather believe it's made of cheese.
Click the image for a large version.
I took this picture of the moon back in 2014, while sitting on Panama City Beach. I am quite certain it was high overhead in the sky slightly to our south-east, as we often see it when we visit the beach on late-summer evenings. It is dark where the picture was taken, because it was already past sunset in Panama City beach.
The picture proves several things:
1) The moon is a globe, and not a disk, as clowns like Eric Dubay insist. The moon is only partly visible because it is high overhead, and the sun, which is below the earth's horizon far to our west, is illuminating that part of the moon which faces it. That proves that the moon is a globe. [Anyone can reproduce the effect with a flash-light and a ball.]
2) The earth must be a sphere, because the sun dropped below the horizon at sunset. But because the moon is very far overhead, the part facing the sun is still being hit by the light of the sun, while it is dark on the ground below.
3) The earth must be a sphere, because we are in the dark, yet the moon high overhead is still being hit with light from the sun even though the sun is below the horizon. We observed the sun drop below the horizon, and therefore its light does not hit us simply because the mass of the earth is now between us and the sun.
4) These flat-earth clowns insist that the sun is a disk which can be far away, yet not illuminate an area unless it is fairly close to being overhead, because it is a disk and its light shines downwards. But the light here, which is only seen on the part of the moon facing the sun, proves that claim to be wrong. If the moon were being illuminated by an overhead sun on a flat earth, Panama City Beach would also be illuminated in that same manner.
So here is some simple math:
Reasons 1+2+3+4 = Flat Earthers are ABSOLUTE IDIOTS.
