Q: just how old is this rock we call earth
Myself i feel its closer to about 12.5 14.8 billon Bp.
What makes you feel that? Have you read any of the science that leads to
the conclusion of ~4.5BY? Do you have any evidence to support your
feeling that the Earth is three times older than that?

Yes, Silucates last in o2 for no more then 250-300 millon years, and
the land masss have turned over about 3-time thus far. hydrated
silucates have a very short life span.

Rethink this part of your premise. I've got lots of 1.5 billion year old granite and rhyolite, looking very much like the day it cooled, and some
Gunflint chert (mostly quartz) between 1.9-2.3 billion years old that is perfectly suitable for turning into an arrowhead. I've got 375 million year old chert too, some of which is as bright and shiny as you please, and some of which is almost all weathered to tripoli by now. The granite, the rhyolite and the chert all spent some substantial time underwater, and therefore theoretically hydrated.
