How Come Nobody Ever Told Me The Earth Was Not Flat?

I am very upset as watching the You Tube clip featured above made me realized that the Earth might not be flat after all. This miniature documentary actually states that we are only a few to believe the Earth is flat. I am in shock. How come nobody ever told me the Earth was round? It seems like a major scientific fact eluded me for so many years. Now that I've discovered the realm of the "Stuff They Don't Want You To Know" podcasts, I'm just gonna watch them all and bring my knowledge of everything that surrounds me to new heights! Expect Power Posts in the next few days as I'll be taking advantage of my new found expertise to become even more insightful.
