Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it. When we enquire into any subject, the first thing we must do is to know what books have treated of it. This leads us to look at catalogues, and at the backs of books in libraries.
‒ Samuel Johnson, 1709 ‒ 1784
So when you hear some conjecture that doesn't make sense in the understanding you have acquired from education and experience, ask those making that conjecture to provide the references in support of their claims. Without references, bibliographies, books or chapters in books, peer-reviewed papers (not letters to the editor), conference proceedings, it is unlikely that the conjecture has any validity outside of a personal anecdote.
While those personal anecdotes make good dinner conversation, making decisions, especially decisions that require spending other people's money need evidence.
Extraordinary claims require extraordinary evidence - Carl Sagan
