Research is not equivalent. Just because two people make an argument does not make them equally valid. Unless you are a medical researcher you're not meant to somehow know how medical research papers work and what their results are on your own. It's not black and white. It's the same as trying to take electrical engineering papers and base opinions on it without any knowledge of the math or how it works.
All configurations could have an infinitesimal chance of occurring, but one configuration could still have a billion to one chance of occurring over another particular configuration.
Which is especially relevant if we have a relatively recent basepoint of comparison.
An infinite number of monkeys with typewriters might eventually reproduce Shakespeare, but 10000 monkeys doing it on their first try points to causation beyond "chance".
