My intuition has always told me that Satan is a control mechanism that was created by the Church to control others by "fear". I will stick with that belief until I am "proven" wrong, however long that shall take!
What does your intuition tell you about 'gravity'?
What does you intuition tell you about the ubiquitous and inevitable 'adversary' and 'deceiver' that presents itself constantly?
What "Church" are you talking about? Islam? Catholic/Christian? Hebrew? Buddhist? Hindu? Taoist? Shamanist/tribal?
