You know, because you've been told, that the Earth revolves around the Sun. You also probably know that planets other than our own have moons, and the way to test to see whether or not something is true is by experimenting.

Mitsumasi Anno grew up in a traditional, beautiful Japanese village named Tsuwano, far away from any bustling city. Although he and his family lived near the sea, the mountains all around kept Anno from experiencing its vastness until he was older.

Once you start thinking about geometric shapes, you'll find them everywhere.
