Everything seems to fall straight down on earth because it is ROUND the shortest distance to the center of earth. So tell you friends things would fall at different angles if the earth was flat because since gravity pulls toward the center objects falling near the sides would fall at nearly 45 degree angles and THINGS DONT you idiots! Everything falls straight down because earth is round and the quickest path toward the center is STRAIGHT DOWN.
Also explain this. If gravity doesnt exist. What happens to an apple that falls off the edge of the earth? What pulls it down? What causes the apple to fall if gravity DOES NOT exist?
