What the moon can teach us is the part of our own story we cannot find anywhere down here, because this planet erased it. Every earthquake, every ocean, every million years of weather. The very forces keeping us alive have been destroying the oldest rocks on the surface since before life existed. The first 500 million years of Earth's history, the period when life was first trying to hold on, is simply gone.

What does it feel like to realize the answer has been sitting in plain sight every clear night for four and a half billion years, undisturbed, waiting, and we have only visited one patch of it? The six Apollo missions all landed in roughly the same region. It is like saying you understand Earth because you have been to Canada. The far side had never been touched by anything human-made until two or three years ago.

There is a crater at the south pole larger than the distance from Vancouver to Winnipeg. We cannot even agree on when it formed. That uncertainty is not a gap. It is the whole question.
