The devil is a religious concept. He is an aspect of religion, not the creator of it. In an effort to understand the world around them, humans applied supernatural characteristics to the things they saw everyday but couldn't understand or control. These things had a great deal of power over the lives of man--storms, earthquakes, landslides, volcanoes, wild animals, etc. It was natural to assume that these were the product of some will--whether wills of their own, or of some entity that controlled these things. In order to please or appease these 'entities' humans designed rituals that they believed would put them in good favor. These structures of rituals are religions. Humans created religions--and all the gods and devils that come with them.
