                                    the fallen-down-ones because these tall celestial beings fell from the sky. Their half-breed progeny and their
                                    descendants are often mentioned in the early books of the Old Testament until the last of them were finally killed off. They
                                    were known as the Rephaim, Emim, Anakim, Horim, Avim, and Zamzummim. Some scholars speculate that this tradition of giants
                                    born from the union of gods and humans formed the basis for the demigod of Greek mythology."
