I agree Luis. And I wanted to add that I interpretted the list as being a compilation of people who have influenced history aside from their effects upon religious and spiritual beliefs. The summary of how many people belonged to which religion might be a little misleading in that way. These people influenced the world not just via philosophy but also by methods resulting in physical actions. For instance, I had read a comment at the other forum disagreeing in regard to why Hitler was placed so highly upon the list when compared to some of the other names. Like it or not, Hitler had a very profound effect upon history, some of his actions still influencing the world today just as much as many others on the list. Muhammad was also selected as number one for both religious and military achievements.
