I had an outerbody experience when i was young. Ive experienced the impossible. I know people that see things others cannot. Things like these are not caused by chemicals and call for a higher awareness. We already do things beyond our knowledge with computers. If what you say is true we could simply plug in just a sample of every reaction in a computer and make it predict the outcome. We already do this on some level with business...just take a business calc course. Have you studied the naturally occuring factor of "e" in nature? We can program machines to pick kernals of corn because we can predict exactly where it would go. Why are you ignoring chaos theory and probably many other theories i cant name? How naive and human a thought that everything is pre-determined. What do people want to naively bring down existence down to simple chemicals and ignore the unexplainable? Its silly and its man once again trying to play God.
