I don't believe that in those days he did. I believe that God was so totally fed up with humankind that he decided that they would no longer live longer than 120 years. It took a while for the shorter lifespan to show up but it did eventually. Now as you can see, most people don't even live to be 100 years. There are a few who do but for the most part not. mankind is sinful in nature, and so I feel that God just didn't want to have to deal with the long life of the extreme sinfulness that has been seen since the beginning of time. Too Bad too. What do you think?
God Bless you in your search, and may he grant you the wisdom to find the truth
