I'm a near-total ball-earther, and I can't find any flat earth model that remotely "works." That said… I see some possible "helper-crumbs" around here (and maybe elsewhere) that make me wonder exactly what they're deceiving us about re: earth/space. We're being lied to about some aspect (cuz duh)…just don't know about what exactly.
