According to the experts, the Holy Bible teaches that in prehistoric times supernatural beings cast out from Heaven visited Earth, interacted with mankind and even mated with human females to create a race of superhuman demi-gods or giants. Fortunately for mankind, the offspring of the fallen angels were judged wicked by God and wiped out in the Great Flood. But the influence of the unholy visitors helped shape early civilization. This could explain how people like the Sumerians of Mesopotamia appeared out of nowhere around 3500 B.C., bringing with them a pantheon of deities, the first written language and a superior knowledge of earth sciences, Horn says. It may also explain why many of the religions that followed Sumerian mythology, including Greek mythology, emerged from the original idea that powerful beings with names like Zeus and Apollo visited the Earth, intermarried with women and fathered half-human warriors.
Most people today see the gods of Egyptian and Greek myths merely as fictional characters.
But the Bible makes it clear that the false gods were actually evil spirits. The scriptures say, Those things which the pagans sacrifice, they sacrifice to devils. Over and over again, the Bible makes it plain that behind those carved idols were spirits whose purpose was to draw people away from the one true God. For example, in the New Testament, St. Paul encounters a Greek oracle a priestess who allowed herself to be possessed by Apollo in order to pass on prophecies. The Bible states, Paul being grieved turned and said to the spirit, I command thee in the name of Jesus Christ to come out of her.
