"The rationale makes no sense" cannot be used to disprove something with lots of unknowns. Of course having a theory that match current understanding would be helpful.
Good thing I wasn't trying to do that. What I was doing was arguing the statement "The rationale makes so much sense" is bullshit. No, the rationale made no sense. It directly contradicted what was known. Now, sometimes things that make no sense turn out to be true, but that's very rare (especially when the newly claimed thing requires not one but multiple miracles to be real), and not what I was addressing.
