I've wondered before where Cain got his wife. Could he have already been married when he killed Abel, or did he get a wife after going into his exile?

I also wonder about things like: did he see his parents again? Did he ever sacrifice again?

It's strange to think that people could have been living for 800+ years. Even though death had been introduced to the world, life was still so strong that they lived for almost a millennium! At the point where modern people are dying off, people then were still youngsters.

More wondering: what's it going to be like to live for eternity? :)
