Evidence of Advanced Civilizations living on Earth more than 100,000 years ago?

I've never heard this before. How would Earth "lose" the moon?

It was from the glancing impact of another planet, taking a slice off the Earth that later became known as the Moon..

If the earth gave birth to the moon, then there must have been a gestation period. Sort of like a pregnancy. So something must have impregnated mother earth. So who is the daddy?

Ok, let's pretend the sun doesn't implode. The moon can detach from orbit? Seriously???! Would it then orbit the sun?

The moon may have reversed direction and is now spiraling inward toward the earth. Scientists discovered in 2020 that the earth's rotation speed sped up. There is no general consensus on why this is happening. But we know a spinning ice skaters rotational speed will speed up when their arms are pulled inward.

No.
Like I said, the Moon will stop receding once the Earth and Moon are fully tidally locked.
You know the Moon always has the same side facing the Earth, right? When we are fully locked, the Earth will always have the same side facing the Moon as well.
At that point, the Moon will no longer be receding.

One other point - the Sun will not implode.
The Sun will become a Red Giant star and will engulf Mercury and Venus - probably Earth as well - but possibly not Mars.

Actually, we absorbed the iron core of that other planet, so it wasn't glancing.
If that hadn't happened, we would probably not be here.

If that other planet was larger than about 60 miles and had hit us at full force, we wouldnt be here right now...Blimey even a sizeable asteroid could wipe us out, let alone another planet that we have no idea of its actual size Hartey...Therefore i shall stick with the adjective Glancing, and of course you have the right to post your own conjectures ..

I missed that part. Thank you. I didn't think Earth could actually "lose" the moon. Won't the sun implode when it dies?

If I may.

The sun won't implode (right away), but will expand when it comes to the stage
where it has used up the hydrogen from its core and then will start to use its helium.
This forces the transition into a Red Giant.

IIRC, It will expand out to somewhere around 1 astronomical unit,
which is considered to be the current average Earth-Sun distance.

This means the Sun will gradually engulf Mercury, Venus, and most likely Earth.

After about oh, another billion years......
the sun WILL EVENTUALLY Shrink into a White Dwarf
and give off much less energy than it did when it was a 'Class G Star'.

Stellar classification, scheme for assigning stars to types according to their temperatures as estimated from their spectra. The generally accepted system of stellar classification is a combination of two classification schemes: the Harvard system, which is based on the star’s surface temperature,

The Earth wasn't solid at the time.
Glancing doesn't get us the extra iron core we have (and the Moon lacks.)

No. It will grow immense in size. becoming a red giant.
LONG after that, it will shrink back and become a white dwarf star.
