Without meaning to offend anyone, I do claim that we mere mortals can also come up with a meaningful creation myth. Well, “myth” might be the wrong word, but how about taking a stab at answer this question: How did we get here?
Were gods sitting somewhere up very high, waving wands and creating the cosmos and our planet? Did an egg crack open and give birth to a variety of demigods who continually battle with each other for supremacy, while we mortals struggle to stay alive amid forces we don’t understand? Did some feisty amoeba get a bunch of friends together to organize a larger being? Did the eternal forces of lightness and darkness crash into each other, creating matter and ultimately human beings? Does a trickster god lurk in dark matter, waiting to pounce when we discover his/her existence? Did a comet hit a cooling rock and let loose little gremlins? Who was watching all this?
I often think much of fiction is about writing a version of the fables of old. Try one!
