I would have Adam dwelling on earth well into life of Lamech... But not long enough to see Noah... Lamech should have gotten busier earlier!3 And Adam lived an hundred and thirty years, and begat a son in his own likeness, and after his image; and called his name Seth:
4 And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:
5 And all the days that Adam lived were nine hundred and thirty years: and he died. - Genesis 5
I tried to chart the genealogy. I have Lamech passing away five years before the flood.
