There’s still tons of Roman structures standing today.

Imo, there’s a massive difference between a few aqueducts or cobblestone roads still standing from the fall of the Roman Empire and the GARGANTUAN stones that were manipulated to construct the megalithic sites of the world, which like the Sphinx (7-9000 years old MINIMUM) has now proven, are likely even far older than their dates of creation claimed by academia.

If the Romans could have built structures as impressive and long lasting as those who came before them, they would have. But they didn’t. Human history has been demonstrably on a downward trajectory since the earliest evidence we posses, once you overcome the non-sense that is “the fertile crescent was the first emergence of agriculture ever, roughly 10,000 years ago”
