3. Yeah, but it would be a part of common knowledge by now if people came off the edge.
Ever heard the expression "He just fell off the face of the Earth"? Now it's just an expression meaning "we can't find him", but in the time where the majority did believe in a flat Earth, people were reported as falling off the Earth many times. Although, odds are they didn't because of the ice wall.
4. I've never seen or heard about any 150 foot wall of ice.
That's because I don't think it's been encountered yet. If you look at this model of the flat Earth:
You can see that it is bordered by the South "Pole", which is shown as a large strip of white. If you compare the thickness of it to some place on the Earth, you can see that it's almost half the width of North America. So, it's just so large there, that no one has actually made it to the wall yet. Even in the round Earth mindset, people haven't been that far into Antarctica.
5. If it wasn't, then there would never be satellite interferences by weather, and the government wouldn't bother spending millions of dollars on radio towers or satellite dishes.
Odds are there are satellites, simply because they demostratably make things work. They get launched up outside the Earth's atmos-dome (not a sphere
) and orbit in a circular motion with the North Pole serving as the center. Much in the same way as I demostrated the sun does in another topic, but at a much lower level.
6. The Sun is too far away to shine on certain locations. If it's only dozens of miles away like you say, it still would cover a huge amount of land at a time being as bright as it is.
You're assuming that what is currently assumed to be true about the sun really is. The sun is actually much smaller, and much closer than previously assumed. It is also much less powerful. It therefore cannot shine on the entire world, but only parts of it as it rotates at a high "orbit".
