The endosymbiotic and colonic human archaea secrete RNA and DNA viruses and serves as a reservoir for them. The colonic and endosymbiotic archaea also generates RNA viroids which are converted to DNA viroids by colonic epithelial HERV reverse transcriptase and gets integrated into the colonic genome. The RNA and DNA viroids hybridise with the viroidal and bacterial population of the gut microbiome and virobiome DNA and RNA of the gut leading to generation of new emerging viruses in the homo neanderthalic species producing pandemics and extermination of hybrid homo sapiens which are not resistant to them. The homo sapiens become an extinct species and the homo neanderthalis will dominate the earth. The origin of the archaea and the RNA viroids are possibly from the interstellar space as archaeal clouds and RNA viroidal quantal computing clouds which function as extraterrestrial intelligence. They would have reached the earth via meteoroidal impacts and seeded life on earth. The present COVID 19 pandemic could thus have an extraterrestrial origin.
