Matt points to fluvial channels cut into Egyptian limestone and argues that no rainfall in the last 5000 years could account for them, even though archaeologists attribute them to wind erosion. His guest notes that the ancient Egyptians recorded a dry climate, while in his view Egypt had a rainy season and green land before 9000 BC. Water and humidity are the main enemies of limestone, so to him heavy erosion like this points to conditions far older than the last 7000 years. For Matt, that would mean a missing chapter of history far longer than the one we are living in now.
