Question: Why does the Earth seem flat?

Ryan Cheale answered on 24 Jun 2015:

If you look out your window it seems flat because locally the curve of the earth is small so you can’t see the bend. But if you ever go and fly or if you ever go on a ship look out and you’ll see at some point you can see like a cut off? That’s where the curvature has become too much for us to be able to see.
