First 9 minutes are off-topic.
You do not need 'lunar landings' to get samples of moon-rocks
there are way more on Earth than were brought back by the Trekkies.
The age of Uranium is the premise on which the model for the
age of the Earth is based, so all that can be concluded is that
the Uranium formed 4.5 billion years ago.
The state of the Earth before then is unknown.
The theory on how the moon formed is total junk anyways,
because if an object collided with the proto-Earth,
and ejected a moon-size object, that moon would return
to its origin; as its orbit would have to be almost perfectly
elliptical. That moon has no reason from gravity to stay in
a stable orbit; so the theory fails from basic gravity 101.
Moreover statistically, every major moon in the solar system
formed by such collisions? How did Galilean moons form by
collisions with a 'gas-giant'? And when they did this, it
was all miraculously coincidental that all those major moons
ended up orbiting in the same direction on the ecliptic plane?
That there are fundamental flaws in basic logic here, is every reason
to doubt the more complex aspects of the argument that we
are just expected to accept on good faith.
Worse than this is their theory on how the solar system formed
from random collisions of dust and gas. That could never result
in planets so diverse in minerals as we find them. Their reasons from
gravity for how the solar system formed are also blatantly illogical
as we should expect random collisions to result in planets
rotating on axis and orbit in all manner of directions.

. So for Earth to be a bit over 6000 years it's like a freaken skeleton in a coffin already!
