The Herculaneum Bread Loaf

Stamped sourdough bread probably isn’t the first thing you think of at the mention of historical artifacts. The Herculaneum loaf was baked just before the eruption of Mount Vesuvius in 79 AD and discovered in 1930 after the excavation of the House of the Stags. It is currently preserved in the National Archaeological Museum in Naples.
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?
