Credulous? For not resorting to the "My Invisible Friend" explanation just because a particular non-magical scenario isn't nailed down? Shouldn't claims involving supernatural beings be the ones that have to be nailed down solidly?
Why provide anything that is rejected a priori?
Yet here is the argument to which you are blind.
The recognition of the fundamentally biological nature of genetic change and of cellular potentials for information processing frees our thinking about evolution. In particular, our conceptual formulations are no longer dependent on the operation of stochastic processes. Thus, we can now envision a role for computational inputs and adaptive feedbacks into the evolution of life as a complex system. Indeed, it is possible that we will eventually see such information-processing capabilities as essential to life itself.
