Researchers have analysed moon rocks brought back by the Apollo 17 mission and discovered water at concentrations ranging between 615–1410 parts per million. That's of the same order as in Earth's upper mantle.
The discovery of lunar water has surprised the evolutionary researchers, "because it contradicts the prevailing ideas about how the moon formed." Namely, the idea that four billion years ago an object crashed into Earth, knocking off a portion which supposedly became the moon. But the collision should have vaporised any water in it.
The Genesis explanation for the origin of the moon has no such problem! (See also creation.com/moonage.)
