How did the moon get closer now then it was back then because the moon is moving away from the Earth now . That doesn't make sense to me

as the sun expands into a red giant it will lose mass, so there is a chance that the Earth will escape this expansion as it enters a higher orbit thanks to the loss of mass in the sun.

But 4 billion years ago the planet would have been covered with water and only some volcanic islands. Pangea hadn’t formed yet

ya know, that expanding sun part had me thinking for a while now. Humans will be so advanced, we'll be able to shift planets to a new radius relative to the red sun.

You know that 25,000km is much, much closer than 384,000km, right?

Wait, wouldn’t the moon being further away cause tides to be lower than they are now
