I found this chart online. Keep in mind there are small errors due to not knowing when in a particular year, each generation was born, and potential different ways of counting ages/years. It is unlikely that it is off by more than a couple of tens of years. The traditional calculated date of creation by Usher was 4004 BC. That should be very close. https://image.nostr.build/ba92e42c593db3525355b6209d407281685fa38f0dd2dead9296863641c53a31.jpg
