First off, I would love to announce I am a believer that the earth is indeed flat.
The proof in this site regales me since it's all made up.
Here is proof of why you guys are wrong (using mathematical methods certified by the World's smartest minds)
E = 1 + r^2
There we go, now you can't argue against anything I have litigated. Not only does this prove how correct I am, but it also showcases how generations of famous scientists etc are incorrect because some college kids made up some mathematical equations to prove them wrong.
I dare you to prove me wrong, oh wait, YOU CAN'T! Do you know why? Because there is no evidence to prove I am wrong, this is the assumption you guys go upon to base all your "facts".
Also, I have been to the moon, and I've seen the Earth, it is round. You can't argue against this, because you have no proof to say I am wrong. This is shown by the mathematical equation (M = 10/2 X 5^15/3), that equation which wasn't made up, asserts factual evidence I was indeed on the moon.
The world was believed the be flat a long time ago because of a man named "Eron Elong". He wrote a book contending he saw a man fall off the Earth, but the sky was blue and he didn't look down to see where the man went. Not only are all your assumptions based off this book, but the fact the sky was blue (directly infront of him should have been space) and he didn't look down (insinuating he was making a bullshit story up) debunks all your points. Also, it has been well documented that in the early years that people believed you will fall of the world if you navigated too far in 1 direction in a boat, and it has also been well documented that there are "sightings" of this happening. Yet there has been no documentation of an ice wall, that is just conjectured bullshit.
Lastly, you claim that the reason there isn't daylight all the time and why the entire world isn't lit up at the same time (meaning there are timezones) is also hilarious.
Light a fire, and see if that fire can direct its light in only 1 direction. When you can realistically prove that it can, only then will your theory have a meager amount of credibility; considering the Sun is giant ball of flame (can't prove me wrong), you guys have been proven wrong.
With sun rising and sun setting, the known theory is that the sun is stationary while the earth rotates. If the Earth was flat (while it was said the Earth is rising due to some equation that was made up), that would mean the Sun would also have to be rising too, but it can't be otherwise it would perpetually shine on us. If it doesn't rise, then the Sun would be shining on the back of Earth, meaning we would be stuck in nighttime perpetually.
Even then, think about it for a little while. The earth is flat, the sun has to rise and set.
A likely diagram would be:
Earth:
______________
It's like that because it's flat
Sun's movement:
_ _ _ _ _ _
/ \
/ \
| |
| |
\ /
\ _ _ _ _ _ _ /
Has to be circular otherwise sun can't rise and set.
Therefore, a diagram would be:
_ _ _ _ _ _
/ \
/ \
| |
| ________ |
\ /
\ _ _ _ _ _ _ /
That exemplifies that the Sun has to be able to rise and fall (since it's rotating around the Earth, not the Earth rotating while it sits stationary), which is completely unrealistic.
