This is clearly a nod to Erich von Daniken's Chariots of the Gods book.

In which the theory that humanity's 'creator' God was actually an ancient (Alien) astronaut.

It doesn't dismiss the concpet of God, it actually explains it. That God was an advanced being who created and manipulated life through genetic engineering.

This theory is supported through many ancient cultures and religions, including the Summerians creation mythologies.

The scary concept behind this leads us to the modern day Christian Bible... that God, is much like a "man"...

Angry, petty, jealous, lustful, vengeful, etc.

As implied in this classic Star Trek film.

Now, let's take it one step further. Imagine that "God" is alive today and in the flesh so to speak... has the 'personality' of a human with full emotions but is advanced with the power of life/death/creation on a universal scale.

Surprise!

True Story.
