If biblical canon is true , Cain would have been alive in the time of the Antedeluvians, he would have been swept away in the flood and their is a very real possibility he is currently penned to the sea floor, by the immense weight of the ocean in a perpetual state of drowning

Imagine for instance present day humans lived to be 1,000 years old. We certainly could not have everybody living that long now could we? No way. But for those that did live to be 1,000 years old imagine if they had to wait until they were 100 years old before they even had the right to vote, a say in matters, etc. The remaining 900 years would be pretty interesting for those blessed with the longevity of 1,000 year lifetimes, especially if our body didn't get so freaking old by the time we're 50 years of age...

It sucks dogs only live 10-13 years on average because I've had some great dogs that would have been wonderful if they lived to be around 40-45 years of age, and after all, why not??
