How would Christianity have evolved today alongside with other religions if Adam, Noah, Melchizedek, Abraham, Moses, David, and Jesus had lived for 969 years just like Methuselah did?
According to the Orthodox Tewahedo Bible, the largest Biblical canon book up to date in traditional Christendom, God had made seven known covenants with these seven named individuals. If we give these seven known individuals the same lifespan as Methuselah, the longest lived person in the Bible, would that have changed Christianity today and all other religions that Christianity interacts with?
