There's no bayesian reasoning here, just someone assuming something to be proved to be already true. Statements don't become self-evidently true just because someone assigned probabilities on them.
Also, using only past billion occurrences of the sun not blowing up, and then still concluding that the sun will not blow up despite of any recent indications of the sun showing anomalous activity seems a more accurate analogy.
