To be fair, I only pointed out that the earliest anatomically modern human fossil found is around 200,000 years old, not that I recommend playing a character that old. Monumental architecture, the agricultural revolution, pottery and all that is significantly more recent... it's been awhile, but if I remember my archaeology courses correctly, the agricultural revolution/neolithic revolution happened... eh around ~10,000 BCE. Granted, different parts of the world experienced it at different times and went through it at different rates.
Likewise, as you get into more biblical times, the understanding of the size of the world was significantly smaller. If you want an authentic chronology for your succubus, I'd say something like this:
About 10,000~ years old. Existed in a mesopotamian tribal group that dominated the region. There is a theory that back then there was region why experiences of catastrophic flooding, so maybe a catastrophic flood destroyed the rest of the tribal group, and a few other tribal groups in the area: thus seeming like a failed version of humanity getting wiped out. Then build your backstory from there.
