Not sure why this is any point of contention. You can tell a believer anything. You can tell them that the earth was underwater for 40 days and nights, and a guy named Noah went out and collected two of every species of animals and put them on a boat.
Science will tell you that civilizations existed before, during, and after Noah's flood .. thus it could not have happened.
Facts are not required in religion, thus the comparison between religion and science is no comparison at all.
