Not sure I understand your problem? Bill has been making Science cool and interesting for kids for decades. He promotes STEM and hangs out with the coolest scientists. He's learned enough and studied enough to be solid in his foundation. He doesn't say he's a phd and doesn't say he knows that much except how cool it is. He's got a quirky sense of humour and studies what he needs to know. He's spent a lifetime learning and I would say he's got a bachelor in most sciences based on life and experience. Not a bad way to work at life. He loves science and he's the president of the Planetary Society. It's a great resume. Better than mine.

My problem isn't with Bill Nye so much as the cultural shift to treat "science" as a religion. This cultural shift, while initially caused by Tyson, holds Nye as one of its high priests.

The cultural shift I am referring to is characterised by people believing that beliefs held by scientists are unquestionable, or that science "knows stuff" definitively; this is generally presented as a counter point to "religious belief". So, "religious belief stupid/evil, scientific belief correct/good".

But here is the problematic point: science is a process of self-correcting evidence gathering, that I have often summarized as "if you stop questioning it, it stops being science". Science leads us closer to truth because it is a process of questioning, and that is was makes it better than religious belief.

When science becomes unquestionable, it becomes valueless. Bill Nye has become one of the poster children for "unquestionable" science.
