I remember someone saying people who want to prove something are very persistant and loud to do so, although they are not right, while others who think that fact is selfunderstanding don't do anything but then often lose. So it's with flat earth topic too. But there is no such thing as flat earth.
Can you prove the Earth is a spinning globe? Because I have a mountain of evidence that the Earth is a motionless flat plane.
e.g. next time it's a sunny day with a clear sky just wait for Captain Pedophile and his military tanker jet to fly over and start gassing your children. After he lays down a few chemtrails observe (before they spread out and turn your sunny day to hazy shit) that they're perfectly straight and level (no curve). Just one of many proofs.
