...No.
The burden of proof falls on the claimant. If you can provide proof of extraterrestrial communists, literally anything, then I'd maybe be inclined to believe you. But extraordinary claims require extraordinary evidence, something I sincerely doubt you have. Nothing, on its own, can "make sense". Everything requires evidence. Gravity wasn't believed in overnight, miasma theory didn't just disappear when Jon Snow came around, and unless you can provide any sort of definitive proof that extraterrestrials both a. require communism to be extraterrestrial and b. exist and have visited earth, then I'd believe you. But you can, in all likelihood, provide no such thing.
