True, but it's ultimately a matter of perspective: Is a nuclear chain reaction releasing energy at the rate of several million times that of a chemical reaction 'natural', or could it be considered 'supernatural'? Is 'Action at a Distance' (look it up) 'natural'? And what in the hell IS gravity anyway?
The point is, we have no idea about a whole lot of sh!t. But attributing it as some sort of spooky, hocus-pocus probably doesn't do anybody any good or lead to any real/eventual answers to these tough questions. From a rationalist/materialist perspective, positing an "I don't know" beats making up absurdities, in my opinion.
