I am still waiting for a good explanation for why vertical buildings/structures cast their shadows at the exact angles you would predict, at different places around the world and at different times of the day, when assuming that the Earth is round and that the Sun circles around it.

@Lavater I suggest you google Eratosthenes, and then also read the different experiments done, not just by him, but by people in every part of the world.

I enjoy this conversation as long as it is open-minded and driven by a desire to know more, and not just hold onto existing beliefs.
