Answer:
No, the world is not flat. Many people believed the world was flat and not in a sphere shape. Christopher Columbus, a world traveler, wanted to know if the world was flat or not because it has been going on for a while. He asked a queen in Spain for 50 crew mates and 4 ships in each. The Queen agreed with him and off Columbus went on his journey.
Later, he found out that the world we're living in now is r=not flat, it's a 3-D sphere shape.
Hope this helps
