There's a good chance you were taught that the pagan gods were imaginary. But God Himself calls them gods. Not only that, He's judged them, found them wanting, and proclaimed a sentence of death.
In Last Clash of the Titans, you'll discover that the Titans, the old gods of the Greeks, are the Bible's Watchers, rebel angels who fathered the monstrous Nephilim. The Nephilim giants, later called Rephaim, were worshipped by the Canaanites and became the heroic demigods of the Greeks. But the Hebrew prophets Isaiah and Ezekiel, as well as the pagan prophet Balaam, tell us when, where, and by whom they'll be destroyed.
Zeus, Hercules, the Olympians, and the Titans are real. They hate us, they want to kill us, and they're coming back.
