Why do so many people think that 2001 is difficult to understand? The monilith is a communication device, when its uncovered on the moon it warns the powers that be that Earth has reached a stage when it humanity is capable of its own genocide. The Star Child is just a representation of a protective force looking after the Earth.
Thats the way I see it anyway.
