The researchers note that if you take the timeline back far enough, looking 1.5 billion years in the past, the Moon would have been close enough that Earth’s gravity would have destroyed it. That obviously didn’t happen, but since the Moon is over 4 billion years old there was clearly an important piece missing from the data.

What's missing? Admission that the Moon hasn't always been in orbit around the Earth, but was captured in a series of encounters, which also led to plate tectonics.

When the Days Were Shorter
by Larry Gedney
Alaska Science Forum

Present-day nautilus shells almost invariably show thirty daily growth lines (give or take a couple) between the major partitions, or septa, in their shells. Paleontologists find fewer and fewer growth lines between septa in progressively older fossils. 420 million years ago, when the moon circled the earth once every nine days, the very first nautiloids show only nine growth lines between septa. The moon was closer to the earth and revolved about it faster, and the earth itself was rotating faster on its axis than it is now. The day had only twenty-one hours, and the moon loomed enormous in the sky at less than half its present distance from earth.
