“The discovery was particularly astonishing to scientists as the area predates all other finds in the area by at least 5,000 years, suggesting a much longer history of the civilization than was first assumed (carbon dating estimates the site to be almost 10,000 years old).”
More of an argument why not to rely on carbon dating alone than anything else. The ruins are simply not consistent with being that much older than nearby historical ruins that we can date more reliably. There would have been several intervening invasions and cultural shifts if that were true, but that simply isn’t evident when you compare the ruins.
It’s in an area which flooded at the end of the last ice age. And that was about 10,000 years ago.
