From my creation.com link in prior post:
How long has the moon been receding?
Friction by the tides is slowing the earth’s rotation, so the length of a day is increasing by 0.002 seconds per century. This means that the earth is losing angular momentum.7 The Law of Conservation of Angular Momentum says that the angular momentum the earth loses must be gained by the moon. Thus the moon is slowly receding from Earth at about 4 cm (1½ inches) per year, and the rate would have been greater in the past. The moon could never have been closer than 18,400 km (11,500 miles), known as the Roche Limit, because Earth’s tidal forces (i.e., the result of different gravitational forces on different parts of the moon) would have shattered it. But even if the moon had started receding from being in contact with the earth, it would have taken only 1.37 billion years to reach its present distance.8 NB: this is the maximum possible age—far too young for evolution (and much younger than the radiometric ‘dates’ assigned to moon rocks)—not the actual age.
The other 2 articles also were both less than 1 billion years, 100 million and 800 million respectively.
For my money, I’ll rest w/ God’s Biblical statements and say actually only 6 thousand years old and quite likely the volcanic activity followed from Noah’s flood and Earth remnants from the fountains of the great deep hitting the moon. ymmv. :’)

Thank you for your research findings, but ... one thing I learned in my engineering years is that beliefs belong in church.
