[AStrangeMorrow]

As they briefly mention in the article, the dates provided are, to say the least, debated.

Contrary to what they seem to imply the consensus is that the pyramid is much more recent than 10000 years. As a general better be weary of all those "ancient civilization" articles, as they often either fall under bad science, if not straight up conspiracy.

What happened here in short is that they found some organic material dated roughly 10000 years by drilling under the pyramid. Ex: ashes or similar. Instead of concluding that 10000 years ago some humans did a fire here, and that thousands of years later other humans people decided that was a good spot to built a pyramid, they concluded those had to be the same humans. It is like finding Celtic artifacts under the Eiffel tower and concluding it had to be built 2400 years ago
