One thing is certain, the Dragon/Satan is a created being; one of the most exalted type.

         Before his rebellion, he was "The Anointed Cherub that Covereth". He was the protector of the "Throne of God."

         He was perfect in all his ways from when he was created to the day iniquity was found in him.

         He was the "fullness of wisdom" and the "perfection of beauty".   But all that caused his downfall 'pride'.
