evidence: Remains of supposed "non-human" beings were presented Tuesday to the Mexican Congress by a self-proclaimed UFO expert who has before presented alleged alien discoveries that were later debunked. [...] Some of Maussan's prior claims have proven to be false but earlier this week, the famed journalist and self-proclaimed UFO expert appeared before Mexican lawmakers, where he presented the remains of what he claimed were two ancient "non-human" alien corpses. The bodies, he testified, were retrieved in 2017 from Cusco, Peru before radiocarbon dating revealed them to be up to 1,800 years old.
