I’ve known my share of Ph.D.s and the majority are dumber than a box of rocks.
The appeals to PhD's is an appeal to someone with specialized knowledge. But, when the specialized knowledge is on a subject that is already boxed in by the "laws" of a presupposed version of the cosmos, one has to really question whether such an "expert" is a good source of information. At that point, their opinions really have no more weight than us "youtube armchair experts and conspiracy theorists".
You have to first accept a specific cosmology before you can start making truth-claims. And the cosmology accepted by modern science contradicts that of the Biblical worldview (the true cosmology).
