You are, of course, totally entitled to your religious beliefs. However, the oldest historical culture is the Sumerian, which arose in the Mesopotamian region (the delta region formed by the Tigris and Euphrates rivers) about 6,000 years ago. We know without any doubt that human pre-history extends over 200,000 years. The oldest modern human skeletal remains found so far date to 195,000 BC. There are numerous fossilized modern human skeletal remains, and artifacts such as tools, artwork and ceremonial burials, that have been found around the world which are tens of thousands of years older than the "10,000 years of existence" you cite. A few examples:
Bitumen-coated flint implements as old as 40,000 BC. have proved that Neanderthal people in the Syrian desert used it to fix handles to their tools.
Modern human skeletal remains dating to 42,000 years ago have been found in China.
The earliest known European cave paintings date to 32,000 years ago.
Stone tools made by hominids have been found dating to about 2.3 million years ago.
Neanderthals, and later modern humans, used a variety of tools and buried their dead during the Middle Paleolithic era from 300,000 to 30,000 years ago.
Human human artwork and language extends back at least 50,000 years.
By what means are things dated?
