Rochelle,
What, exactly, is the point of throwing out the very possibilty that there are factors, approaches, possibilities and realities that we don't yet understand or know how to measure?
Quite the opposite. Science is about discovering all these forces and energies, and it has been an extremely successful project in doing this.
Science has a principle, though, that supernaturalists find it hard to accept: you need to test your beliefs, trying to find ways to falsify them (this means you need to find a test that would, if the theory was false, demonstrate it to be such). Supernaturalism simply rejects doubt, for emotional, not rational, reasons.
If you see everything in black and white ("It's not proven yet, so it doesn't exist"), I believe you limit yourself just as much as people who only see the world through Bible-colored glasses. I just can't think that way.
That is, I am sad to say, just a convenient straw man allowing you to not deal with the fundamental question, which is: What is sufficient evidence for accepting a theory? Supernaturalists consistently refuse to deal with this question, preferring cloudy slogans and foggy thought.
Science is as far from black and white as you can come. Indeed, science only deals with degrees of probabilities.
What you are de facto saying is that believing something just because you want to believe it is superior to requiring justification and evidence. How can you otherwise call it "black and white-thinking" to require some solid evidence for claims that are indeed quite extraordinary?
