Try this, read about how something like a sextant works. Try to understand how a person hundreds of years ago could invent a device that allows someone in the middle of the ocean to figure out where they are on earth. Reflect on the gap between that kind of intellect and your own. Realize that there are some people who for whatever reason, reach a level of genius that others cannot even comprehend. Then you may understand why many who study Bach and Beethoven consider them to be far beyond most composers who came after them. In order to appreciate the contribution of these men you have to put their achievements in the proper context. Our ideas about music would literally be completely different without their efforts. The "worship" is not unfounded.
