A 60,000-Year-Old Mammoth Tusk

Property owner AMLI is credited for the discovery of a Columbian Mammoth tusk fossil at their apartment development site in Seattle. Regarded as the largest and most intact tusk discovered in Seattle, paleontologists estimated it to be over 60,000 years old, with its exact age to be determined using carbon dating. It was carefully removed for preservation by the paleontologists and eventually found a home at the Burke Museum of Natural History.
I'm wondering, if s/o writes:
"Faaaake - how can it be?
The US exist since 1776-07-04 ! Nothing can be before!
Don't be a woke leftist, do your own research, touch some grass and never trust science or the universities!"
Bomb! What the fuck?
