I have to agree with Rob. Occam's razor is so very often misused it's not even funny. And I say misused because as a general principle of logic, it's basically sound, but those that use it most often usually fail to understand what it actually means or in what context it is meant to be applied and just use it to prop up a straw man argument or try to shift the burden of proof.
They also fail to appreciate that it's a philosophy
and not a fundamental law of the universe.
I ask you, what is the simplest explanation for where babies come form? An efficient and discrete avian based delivery system, or a series of complicated biochemical interactions based on billions of years of cellular evolution through an essentially random and chaotic process of natural selection? The stork idea is certainly simpler, but does invoking Occam's razor make it correct? Of course not.
