Life in earth would have evolved by seeding of viroids and archaea from the outer space consequent to asteroidal hits. The quantal computing cloud in the intergalactic space made up of archaea, viroids and porphyrions can seed organisms into the earth off and all through asteroidal impacting infusing a fresh set of genes into the planet and regulating the planet organization & function. The various pandemics that occurred in the various phases of the history of the earth would have an extraterrestrial source. 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. The RNA and DNA viroids & gut bacteria can also hybridise with human genomic sequences. This leads to generation of new bacteria, RNA & DNA viruses producing pandemics & extermination of homo sapiens.
