We humans, with our pattern-seeking brains, are always finding patterns wherever we look - even when those patterns aren't actually there. The ancient Greeks saw shapes in the stars; children see shapes in clouds. The Judeo-Christian-Islamic mythology is a collection of folk tales cobbled together over thousands of years. Most of them are clearly the incoherent ramblings of illiterate goat-herders who knew little and understood less. Looking for existential meaning in the Bible is like looking for existential meaning in a pile of Lego bricks. Try hard enough and you'll convince yourself you're seeing something. But in the end, it's just a random collection of meaningless objects. At best, the only meaning such collections of folk-myths have is to remind us once again of our extremely limited intellectual capacity as a species.
