I think empirically, scientifically, materialistically, and pragmatically rather than metaphysically, dogmatically, supernaturally, and paranormally. Genesis has been rebutted by science. The origin of man did not come from creation of Adam and Eve but evolution of species from simpler forms over billions of years. The origin of the universe did not come from a Creator god over seven days but from the Big Bang. The earth came from the accretion disc of the sun just like all the other planets.
Christianity and the other religions are now be included in textbooks on mythology. Jesus, Jehovah, Allah,, and Mohammed are now looked at with Zeus as creations of man to help them understand nature and to deter criminal conduct, and also to give guidance on morally correct conduct.
