i repented in 2006 and noticed a double rainbow,my name is michael and this theory might seem strange. my theory is the rainbows used to hold darkness and light. ie married and single. ie Michael and Samuel. m and s. God said he parted the waters from the waters,and the firmanent was good. ie God liked single and marriage. you can take which is darkness and light at a pinch. so the atan seed sinario is debunked,unless the end of humanity went back in time. and if so the future holds the athiests.oops sorry scientists,oops pardon the pun. it seems a reasonable explanation what says you.?
