You confuse the "opinion of experts" with the scientific process. A hypothesis is just a statement to be tested against reality. We don't automatically have to assume it is true. It is literally someones untested opinion. All that matters in science is the truth about the underlying reality, i.e. the experiments that verify the hypothesis. You are angry that people aren't somehow placing this hypothesis on a pedestal by mere appeal to authority. But science doesn't work like that, that's academia.
