Yes, I do take it with a grain of salt. I'm a scientist. I take all hypotheses with an infinitely large grain of salt until they are tested.

If it hasn't been tested, it isn't science.

A bunch of hypotheses isn't science, especially if it parades itself as something else (in this case by omission), and when there are obvious alternatives (for example, who is to say God wasn't initially conceptualised as a consequence of the evolution of self-awareness and rationality giving rise to the question 'why is the world designed to provide everything I need' and the answer 'a magical being who cares about me' in lieu of knowledge of natural selection?).
