- Seasons are not caused by the Earth being closer to the Sun in the summer than in the winter and in fact, the Earth is farthest from the Sun when it is summer in the Northern Hemisphere ?
- or that the Great Wall of China is not at all visible from the Moon despite being commonly claimed so ?
- or that humans have more than the commonly cited five senses ?
Me neither !
