Well, that's certainly true. It's also true of Aristotle's spontaneous generation...eels growing from horsehairs and so forth. After all, the eels had to come from somewhere, didn't they?
A good model is good, it's true, but it's only a model. It still remains to be proven or disproven.
Except Aristotle never provided evidence for spontaneous generation, never conducted experiments, and did not follow the scientific method. The philosophy of science as we understand it is relatively new.
