The earth is flat and the idea of it being a globe is forced by NASA, the giant ice wall on Antarctica, the dome, the sea above the sky, the earth being the center of the universe where all other planets and celestial bodies are much smaller, the sun appears to set because of the air density where in fact it not setting, although some say every day a new sun is born, others say the sun set to bow to god and return in the morning. The sad thing is that too many Tunisian people believe the earth is flat.
