Truth is Spherical

When this world was younger, we had just arrived at this blue beautiful place. Our eyes just taking in everything curiously. Amidst attempts at survival, we had time to examine things around us, explore, create and build things. Our eyes showed us the vast stretches of flat plains with towering hills. Our eyes told us that we lived on a flat world.I wonder when someone realised that our eyes have tricked us :). May be they still trick us. It is probably their nature to do so.
