Not at all!!! For example, we used to believe that the force that drove a compass needle, the force that destroys your house when it's hit by lightning, and the force that presses back against you when you push on a wall were all different things. Now as science has advanced and we've learned more, we learned that all of these things (as well as many others) were simply different manifestations of the same thing, namely the electromagnetic force. Furthermore, we learned that all of these phenomena can be described by a set of FOUR EQUATIONS. In fact, adding the equation for universal gravitation, we've learned that most of the phenomena of human experience can, in principle, be described by FIVE equations. The entire history of scientific inquiry has been one of simplification and unification, not one of increasing complexity. It may seem, to a non-scientist, that things are more complex, but to scientists this is not the case.
In a way, you are proving my point. With things like gravity or lightning, the more we've learned about them, the easier they are to understand. But with things like DNA, the Cell, and the unique congruence of "coincidences" that occur on earth in a way that is capable of sustaining so much life, the more we learn, the more complex things get.
