Hi Bionic boy You are spot on with your thoughts and with my way of thinking. Our Earth was visited many thousands of years ago and altered . then there could have been another return to have a look with the promise to return . The inhabitants then believed that those Gods would return again .They built structures called churches with spires on them to reach to the heavens as a guidance to come back here . I am not an athiest but instead of believing in the one God I believe that there were many gods. Cheers Towie late at night I do not want to offend anyone who has other beliefs. I am in no hurry to go there and find out DYOR
