Invasion Earth

Based on the Tablets of Enki, translated by Zechariah Sitchin, the story starts with the destruction of seven cities during the last War of the Gods. Ninurta is tasked with using nuclear weapons to destroy the Mission Control Center and spaceport in the Sinai Peninsula. After completing the mission, his wingman, Nergal, is filled with blood lust. He destroys five cities surrounding the Dead Sea. The fallout from the weapons of mass destruction kills everyone in Sumer who haven't evacuated in time.
Four hundred and fifty thousand years ago, the Nephilim cross the celestial heavens in search of gold to save their planet. Alalu finds it on Earth. It is salvation for his people and a kingship for him.
The Nephilim come to our solar system and establish a base on Mars, and a colony on Earth. Trouble comes from the Anunnaki workers working in the gold mines, when they revolt. To end the mutiny, Enki finds a solution. His solution is to create primitive workers who will replace the miners. He finds these primitive beings—hominids—and captures them for experimentation. He hopes that by altering their DNA, an evolutionary jump will create the workers the Anunnaki need.
This temporarily brings relief to the miners, but a growing population, and disputes between the Anunnaki leaders set off a chain of events that leads to a struggle that will settle, once and for all, who shall inherit the Earth.
