>>115300003No, dear. The gods of Earth, which include the Asgardians, are actual gods.
At the dawn of Earth's creation, the nascent life-force of Earth itself coalesced into a conscious being, the Demiurge. This being filled the world with life - micro-organisms at the bottom, immense, ethereal beings at the top. These mighty, primordial titans are nowadays known as the Elder Gods. One day, one of the Elder Gods discovered that if they killed one another, they could feed on the power of the victim to grow stronger. Soon, the world was a bloodbath, until only those who would kill to survive were left - and one other, the gentle goddess Gaia. She turned to the Demiurge for help, and he impregnated her; when her child was born, he was the first of a new generation of gods. His name was Atum, and he immediately engaged his older family in battle. Like them, whenever he slew one, he absorbed their life force; he became a monstrous, demonic-looking giant called the Demogorge. Almost all the Elder Gods were destroyed, except for a few who escaped to neighboring dimensions, notably Chthon, Set and Oshtur. Once Earth had been stripped of the Elder Gods - except for his mother Gaia - the Demogorge expelled the divine life force he had consumed and rendered, turned back into Atum and went to live inside the Sun. The dormant life force blanketed the Earth for billions of years, amorphous and blank, as Gaia sheltered and nurtured life on Earth, helping it to evolve. Billions of years later, the first beings with abstract intelligence evolved, and their dreams, aspirations, ideals and fears finally sparked the dormant godstuff into life; and the new pantheons of Earth emerged, prominently among them the Asgardians.
