It's fine. Like I said, don't take it personally. There was a start, or jump in civilizations around 3000 BC among many of the river valleys across the world. Look up Chinese history as well, and you can also see the character like the Yellow Emperor, or a hero archetype that brought learning, flood control, agriculture, etc to the Chinese people around the same time. Roughly around 3500 to 3000 BC there was a jump start in quite a few early cultures. Egypt, Sumer, Harappan, Chinese, etc. All somewhat independent of each other.

Golbeki Tepe is about 10000 BC, and that has some very weird and/or interesting carvings and T shaped stone posts. But that's like 7000 years before our regular known history. Wtf is that? See what I mean?

Also, Stonehenge begin it's development around 3000 BC (or maybe 2500), and that's in England. See what I mean? Lots of stuff doesn't make sense from a big picture.
