About 4 billion years ago. Your point is?<quoted text>
If the moon's orbit is receeding at the current rate of 3.8cm per year, how long ago would it have been just touching the surface of the earth and what effect would being closer have on the earth's rotation, axis, and tidal forces?
Also, you seem unable to address my question.
Why is the moon receding? What causes it to recede?
There is a very simple, common scientific explanation for this. If you are indeed 'on top' of secular science, please supply the answer?
PS: The answer can be expressed in two words
