So the sun is a flashlight focusing it's light in just one direction. Seems like if there's light on certain places on earth, then there would be no light anywhere else in the solar system, since the flashlight sun is only shining on Earth. Or does the sun have multiple beams of light that it shoots only at the planets in our solar system? Is the rest of space completely dark all of the time?

Can you explain to me why we don't have pictures of the back side of the Earth, since it's flat? Or are you going to tell me we've never been to space?

At what point, if i start digging, will i fall into space?

What is on the edge of earth? Is it a waterfall into space, or do i run into a fake wall like on the Truman Show?

Why do we have satellites in orbit? If the world were relatively flat, we could just have really tall antennas to communicate with China, or at least one taller than any mountain in between the points of communication.
