TD is right, the earth doesnt look flat. I keep saying this as well, nobody listens.
Throughout history people have observed it to be flat? I confirmed that observation myself. I have stood with a 360 degree view and slowly turned around looking over sea and land. All flat.
You look over the sea and are able to see land beyond it, are you? Because that is the way every other flat plane appears, isn't it? Feel free to give examples of
ANY other flat planes which have a fixed limit of visibility. List as many as you like.
When you say "the earth looks flat", what you actually are saying is "the earth looks like what I expect a flat earth would look like" because you haven't stopped to think what a flat earth really would look like.
Let's turn the question around - imagine the earth is a sphere. What would you EXPECT to see?
