There’s nothing more to be said.
Such wilful ignorance, stupidity and hatred for the intellect as is displayed by clowns like heppenby, smedley and the rest in their “arguments” can only be diabolical.
For someone who hasn’t gone past high school algebra to in all seriousness impugn the expertise of physicists in their own field - an expertise whose reality is borne witness to every day in all the quasi miraculous technologies we modern humans use - is an astounding manifestation of the sins of vanity and pride, and that of allegations of a world-wide conspiracy involving at least hundreds of thousands of people to “cover up” the “flat Earth” from faked photos, faked video, faked satellites, faked rockets, faked probes, faked telescopes, faked data, faked textbooks, and every physicists and astronomer either in on it or so much more intellectually challenged than “flat Earthers” so as to be duped - heck, flatters even claim that the images of Jupiter and Saturn seems through telescopes are faked by the telescope manufacturers - now that is faithlessness and is verging on a kind of Gnosticism. (Reality is one big lie, and we, the Flat Earthers, possess the hidden knowledge of the truth that will set you free and save you - they literally believe this.)
