I put forth the proposition that the scope of human perception is so limited and narrow that it's utter foolishness to assume that we have unlocked the secrets of the universe in just the past, what? 200 years? It's important to be skeptical...But that does not mean to automatically assume something does not exist until it can be "proven" in a laboratory. True skepticism is NOT taking a stance either way. I'd like to also point out, that so far NOTHING can be proven. The best we can do is disprove something, but even that is a pretty weak way to decide if something really exists. (The same problems with proof exist with disproof...Often it just depends on your specific perception of the object.) Perception IS reality...Don't be so sure that your perception reaches to the ends of the universe, or even to all of the processes that exist just on this planet--We are all taught from a very young age how to perceive the world around us, and most of us believe absolutely that what we perceive is really the way things are...If you are really serious about discovering "reality", you would approach everything with a totally open mind and try to perceive every situation and every concept from as many different vantage points as possible.
