The 'insights' of creation was based on a mythic story that was common to the Mesopotamia area.  The people who wrote the Creation myth, based much of it on the old stories that were told.  They added the crucial part that God brought about creation.  That is wonderful.  But we live in a scientific/technical age.  Most people [and the youngsters in Catholic schools & religious formation] are taught that the universe was created in 7.7 Billion years and the earth in 4.5 Billion years.  Humanity did not begin in a beautiful garden, but evolved from the primate apes and chimps.  People NEED a Christian, but applied/ practical way to understand Christian marriage and family life as lived TODAY.  When Church leaders try to utilize Medieval- 19th Century and early 20th Century answers to 21st Century problems---the result is a people who would rather ask Oprah for advice.
