It's those who are given the stories who mustn't care then...but that is something that we both don't know, and in case of doubt i'd be reluctant to forward that story then. Or at least i'd let them know that the authenticity is dubious.And that we are not 100% sure of, but who cares.
Speciation has been directly observed, and there is plenty of genetic evidence of common descent of e.g. humans and other apes.No scientist has scene evolution of animals
Or do you have a different explanation for ERVs that works at least as well as common descent?
