you have to get your time lines straight as well. Sumer lasted a few thousand years. Babylon lasted about 2,500 years. Rome lasted ~ 1300 years ~ then the climatological event of 535AD happened ~ then it fragmented for good, and no high civilization of equal caliber happened in that vicinity until about 1500 when Michaelangelo began carving marble to the same exacting standards as the Greeks and Romans of Classical times. That's about 1000 years of 'time out'.

Throughout that period people continued to copulate and eat bad diets.

the United Staes will collapse like Rome when a big volcano or comet screws up the weather ~ but we'll be back in a decade since our technology is simply not going to need 1000 years to recover!

An EMP device detonated 400 miles above Kansas would send the US into the stone age, instantly and for years if not decades. Our relevance, our power (outside a nuclear revenge strike) and our history and technology would be over for a long time and we might NOT recover.

It’s Welcome to Mad Max Behond Thunderdome baby!!!!
Leather, shotguns, bare shoulders, and monster trucks will rule the desolation and ruins...

You are forgetting the Byzantine Empire when you say no high civilization existed after the Roman Empire. This empire lasted until about 1450 when the Ottomans conquered Constantinople.
