I looked a little further into this and had two reactions:
1) I was surprised at the depth of explanation and creative thinking of flat earth models.
2) I slapped myself.
Where to begin?
A) If the sun and moon are 3000 miles away and are rotating above a flat earth, both would be visible at all times. Because trigonometry.
Lots of things seem good in theory but go out the window in practice. In reality no object can bee seen beyond its vanishing point not to mention the Sun and Moon have a spotlight effect being projections and all.
B) If there is no gravity, and if the atmosphere isn't rotating along with the earth, and if the earth is accelerating upwards at the rate of gravity, then why doesn't the Earth slam into the clouds, or the sun and moon for that matter?
Wait, who says the Earth is accelerating upwards?
C) If there is both gravity and a flat earth, why don't people at the edges of the earth tumble back to the center?
Scientists still struggle with the mysteries of static cling.
D) Explain the speed of light, e.g. why does light from the moon reach us significantly faster than from the Sun?
Light from the Moon and Sun both travel at the speed of light in whatever medium it's traveling through. How does one go about measuring the age of a photon?
E) Explain wind and tides.
The wind blows as it always has and tides continue to rise and fall, only your perception has changed. The Sun doesn't behave any differently now that you know it's closer than you thought.
How many do you need? I like that people aren't afraid to question conventional thinking, but I'm getting tired of face-palming.
You see the problem here is the devil is in the details, the NASA logo is an anagram for Satan and prominently displays the forked tongue of a snake. Other than evidence provided by an agency born from Nazi operation paperclip as a propaganda tool, there's nothing but the musings of a senile old Greek philosopher to back up the Globe Earth Theory that's regurgitated by the Royal Society. The whole thing reeks of vomit and piss from all the goof they've been drinking.
Keep slapping, eventually you'll sober up!
