I have years of experience in geolocation. My best guess, given the color of the soil and the unique foliage would be Detroit. (It’s a little known corner of Asia, btw.)
The time between now and the Great Pyramids being built is about 4500 years, and the last mammoths died out about 4000 years ago on a tiny island in Siberia, so this 8000 years is like no time at all!
