There are 5 known locations on earth where there exist evidence of an ancient nuclear war . Even the skeltal remains are still radioactive and they are laying where they died. So again, who brought this technology to ancient man. The only ones who we know possesed such technology were the Fallen Angels and Watchers who came to earth 440,000 years ago. They enslaved many human and it’s my belief this is when the Fallen started fighting among themselves which led to nuclear war in the end.
