The Anunnaki came for gold.

For over 400,000 years we have been slaves of aliens.
They founded our religions,
We worshipped them,
We built temples for them,
They made us go to war,
They defiled our women,
They fought with nuclear weapons.
Now they are coming back to Earth.
Their return spells doom for us all in oncoming years we must expect
the Arrival of the Anunnaki.
