The God of the Bible and every other god out there are entirely creations of ancient humans needing to somehow explain events and phenomena in their everyday lives that they did not have the capacity, experience, and knowledge to reasonably explain to themselves. They needed genies to explain the Sun, the stars, weather, life itself. "How did it get here?" "Must be a magical genie of some sort".
The part I can't swallow is why nearly all of these various gods are purported to be the embodiment of love, yet nearly all of them are hateful, vengeful, jealous, smiting murderers.
