What would happen if I told a 9/11 conspiracy tHeorist that there is no physical evidence to support their...?

claims more than 9 years after tHe fact? No det cord, no blasting caps, no remnants of explosives. (there would still be physical remains of explosives all of it wouldn't have been destroyed) No mechanism to channel tHermite to cut steel at that kind of angle which was actually made during the cleanup process. etc etc.
