Orbit in Sonic Gravity and view the universe through the eyes of a madman and you will see that the existence of alien life is self-evident; to wit: interstellar humans with billions of years of experience and evolution beyond what we can comprehend. And when you stare into madness and madness stares back into you, you will realize that you must decide between only one of two origins regarding the human race's arrival here on Exoplanet: Earth. You must decide whether you believe humans evolved over millions of years from the primordial soup with practically no remnants in the fossil record, and the mathematical inconvenience that the 8 billion human population at any exponential growth rate can only be mathematically wound back at most 12,000 years . . . or were you deposited here, perhaps by a divine creator . . . or perhaps by the interstellar human species that placed us here who fly the UFOs we know escape conventional scientific understanding.
