~12k thousand years ago is when it appears we first started to form together into large communities, Göbekli Tepe is a good example. More here https://en.m.wikipedia.org/wiki/Göbekli_Tepe

> This corresponds well with an ancient Sumerian belief that agriculture, animal husbandry, and weaving were brought to mankind from the sacred mountain Ekur, which was inhabited by Annuna deities, very ancient gods without individual names

We find the first evidence of cultivation around 11.5k years ago not so far away in the Levant. Aggrecuture appears to have been the major change which kickstarted civilisation as we know it off.
