I’m not a scientist. The article talks about “ranging from nearly 4 Ga ago to 3.7 Ga ago.”
I am clueless, the article doesn’t teach us lay people what this ‘Ga’ unit is at all.

By the way both Mars and Mercury had magnetic fields that disappeared due to changes in the planetary cores.
The other day I tried to help my son with a science report. The question was: “Why do chicken wing bones and frog front leg bones have the same bone structure as human arm bones?”
Being a middle school science project, I was sure they were looking for an evolution answer. But I tried to search the web to find a theological answer that made sense.
There were only two lines of answers on the web. The 100% Darwin Evolution answer and the God made chickens in man’s likeness 5000 years ago answer.
I don’t think I subscribe to either one of those answers. So as not to look completely ridiculous, I suggested he just go with the one answer that he could get a good grade with.
I’m not sure what faiths still believe in the “God created the Heavens and the Earth in seven days - 5000 years ago” concept but I think that is past its prime.
Perhaps the last chapter of Asimov’s “Foundation and Earth” where the robot R. Daneel Olivaw is found to have been manipulating the goings on of humanity from a base on the Moon for eons wasn’t actually fiction? :-)
The moon and the earth were once a single object.
The moon for some reason is unable to hold a charge, kind of like a burned-out capacitor. Leads me to conjecture that the moon experienced some kind of disaster long ago.
So, what's the sectarian explanation? Because God wanted it that way? Forgive me if I think that makes for a very thin & unsatisfying science book.
