Modern science teaches us the Earth is a ball, with a circumference of about 25,000 miles. Thus, THEIR math shows us that in order to maintain this circumference, there MUST be an exponential drop of 8in. per mile squared in every direction from the point at which you are standing.
OK. So, think this through.
This means if you were to walk 1 mile away from me, the ground you would be standing on would be 8in. below the ground I am standing on. If you were to walk another mile, your ground would be 32in below mine. If you were to walk 3 miles, your ground would be 6 feet below mine! Assuming you are 6ft. tall, this would HAVE TO MEAN that the top of your head would be level with the bottom of my feet. Therefore, tell me again how you can believe that the horizon (which is the ground seen at a distance) could EVER be at MY eye-level when looking straight ahead.
Read this slowwwlllyyyy and repeatedly until it sinks in: IT - CAN - NOT - BE!
Thus, ball Earthers provide the biggest and best proof that the Earth HAS TO BE flat. Imagine the irony in that. LOL! And sorry - pardon the pun - but there simply is NO getting "around" this indisputable fact... of SCIENCE.
Thus, I'm laying down my trump card and shall expect LOTS of apologies from those who will NEVER be able to dispute this fact. Not with math. Not with science. Not with any measure of common sense. Not with Scripture. And certainly not with any form of physical observation (be it in the natural world or the digital realm). It is totally impossible for the horizon to EVER rise to eye-level on a ball.
Checkmate. Game over. Thanks for playing.
