Hahaha... Pardon in my attitude toward this idea because many great and intelligence scientists who already died prove that earth is not flat. The present scientists prove it too. Many books were provided to read in the schools. Books to produce in themaking of newest scientists agreeing to the old teaching that earth is not flat but rather in sphere.
Let's assume that earth is flat so all scientists who are in the space right now are liars.
The truth that provided by great old and New philosophers, scientists cannot be erase in just a moment against discovery.
