About 241,200 years ago is when the first kings of the Sumerian king list started reigning (if I remember correctly). Check this out:https://en.wikipedia.org/wiki/Sumerian_King_List
People say that the Sumerian king list is not legit because it describes kings who reigned for many thousands of years, but that still doesn't explain how near the end of the Sumerian king list, the lengths of time that the kings reigned approaches more 'believable' lengths of time (for example, the last king reigned for a mere 23 years). Also, both the Bible and the ancient Vedic writings describe people with very long life-spans who lived many thousands of years ago. Indeed, the ancient Vedic writings describe human lineages on Earth going back over a BILLION YEARS into the past and there is suppressed archaeological evidence that supports this.
