The previous analogy for having a Flash splash page or a web site completely built using Flash is that of a mime standing in front of a grocery store, and trying to tell you where the milk is.

Well my new one is go stand in a small closet at night after turning all of the lights off, close the door, and now what do you see? Nothing. Absolutely nothing.

If you can’t see anything how do you expect the search engine spiders to?
