We're not told anything about his death, like most of the people in early Genesis. We're simply not told. There's no particular reason to think Lamech killed him, and there's no way he was still alive when the Flood came. In the story of the Bible, then, we can mostly say that Cain, after the murder of Abel, was a nobody who became lost to history.

So i’m reading the bible for the first time and I came across how Cain killed Abel and was set to wander the earth but did it ever say how he died? Did Lamech kill him on Genesis 4:24 or did the flood wipe him out?
