Do you think that Genesis 6:3 was meant to describe a maximum age for humans? Elsewhere in Genesis, it describes people living for more than 120 years after God says this.
Assuming it didn't apply to people living at the time (since the same chapter describes Noah living more than 120 years after this) and assuming that this might have included Noah's sons, we still have:
- Arphaxad (born after the flood, son of Shem and grandson of Noah), who lived to 403. (Gen 11:13)
- Shelah (son of Arphaxad), who also lived to 403 (Gen 11:15)
- Ebar (son of Shelah), who lived to 430 (Gen 11:17)
- Peleg (son of Ebar), who lived to 209 (Gen 11:29)
- Abraham, who lived to 175 (Gen 25:7)
I could find some other examples if you like.
Edit: sorry - I didn't notice the age of the thread. It just came up in new posts when
@Paul wright necro'd it.
