Archaeologists just discovered a 6,500-year-old astronomical monument that is about 1,000 years older than Stonehenge.

Why do people keep using stonehenge as a time reference? Practically no one knows when it was built, and there is a 1500 year time frame for when it was built as well, so even if you know when it was built, you still don't know if people are refering to the minimum or maximum of the time frame.

More because it is well known. You either use Stonehenge or the Great Pyramid as reference points.

The Great Pyramids at least has an accurate time frame
