There will always be the mountain top of great kings, but one will always sit above the rest. When you look at Mount Olympus, it was full of gods, but Zeus sat above them all. In any profession, the question that is always asked is, “Who is the best?”
People will always have a desire to pick the one who has ascended to the greatest level of success in their field. Sometimes there is no clear cut answer, but we will take time out of our day to debate who the greatest is. You can just call it human nature.
