The Devil Made Me Do It?

I believe that science is mankind's way of rationalizing the very thing that cannot be explained. I believe that if everything were explainable, could be rationalized, or even be understandable there would not exist that which is not conceivable and there would not be a need to believe in something greater than ourselves. Let me see if I can explain this further. If a scientist were to test his hypothesis, he would formulate a probable solution to the hypothetical problem that he created. As he gathers data, and uses the data to prove his initial theory, the conclusion of the search would then be a result. Now, is the result a true representation of the initial question, or was the data collected and manipulated to come up with an answer along the lines of his own proposed hypothesis?

If I were to write a paper on how to play the guitar, I would look for sources that support my claim, ones who'd be considered the definitive sources for knowing the instrument. But since I am neither a master, nor the one who created the instrument, can I truly say what it means to play the instrument, even though I gathered the techniques and opinions of the best musicians of the instrument, when the concept of music is endless? There are sounds that have yet to be discovered and melodies that have yet to be played. Even the "masters" (e.g. Clapton, Hendrix, Vaughn, Montgomery, Kessel, etc.) would agree. Would my claim be an accurate assessment of the instrument's possibilities when the instrument possesses endless possibilities? Most musicians would say that they are forever students, meaning all that could be learned is not learned because of the infinite variations that exist.

So imagine if you will the problem I had when I watched a film called "Revolver." At the end of the film as the credits were rolling one scientist said that the ego, in order to have someone to blame created the devil to shift blame upon someone other than himself. That mankind, in his quest to protect his ego needed a permanent enemy to shift blame upon. I believe that mankind is his own worst enemy, thus the necessity for God and his will to be the one that we choose above our own will. When judgment comes to mankind it is the individual that must answer to God, he cannot say that the 'devil' is to blame, when he made the choice to commit whatever act that would be considered evil. So to say that the devil is to blame is not entirely true; I believe mankind is drawn away by his own lusts and desires, and that the devil merely creates an avenue for them to be acted upon. Lastly, a man's years upon the earth are limited. There is not enough time, in a man's life to have a concrete answer to an age old question - is the devil real and is God real, or imagined? Are films like "The Exorcist" that demonstrate demon-possession real or imagined ideas? Are curses real or imagined? Are ghosts and spirits real or imagined? Is mankind's belief or assertion that by asking questions he can eventually come to answer them fully an assertion of the scientist's said ego, or is it that God truly is more than we can imagine and his existence greater than what can be explained? Everything in our lives has an opposite, so for good to exist, evil must exist as well.
