Ancient Christians called Gnostics wrote texts that record an allegory on the origin of the universe which is similar to the scientific understanding of the Big Bang.  Here it is:

Pistis-Sophia wanted to get pregnant without a male counterpart… the result was matter, and it was like an aborted fetus.  In the form of plasma, it came forth like an arrogant and ferocious lion.  It was a she-male hermaphrodite, because it came from matter, and when it opened its eyes, it saw an endless supply of matter, so it arrogantly stated "I am God, and there is no other."  But it sinned against everything eternal when it said this, and so the voice of purity responded, "You are wrong, Samael," which means god of the blind – who is also called Saklas, which means retard.  And the voice above said, "Man exists, and so does the Son of Man."[1]

The parallels with the scientific understanding of the Big Bang are sublimely hidden in this metaphorical allegory. 

     According to science, there was a seemingly endless supply of matter after the Big Bang.  Likewise, in the Gnostic story, there was a seemingly endless supply of matter after the birth of the cosmic demiurge.

     According to science, the Big Bang resulted from a singularity, not a duality, and there is no explanation before it.  Likewise, in the Gnostic allegory, matter resulted from a single person conceiving offspring alone, not according to usual nature, which requires female and male together in duality, and there is no explanation for how such a thing could happen. 

     Another Gnostic passage records that "the primordial matter was cast out like an abortion," and that it "flowed away" from its origin, being "hurled away from itself." Yet the matter was still "in the primordial void, and was part of it."[2]  This sounds a lot like what science tells us about the Big Bang – namely that matter was "hurled away from itself" in the Big Bang, yet matter is still within the "primordial void," that is, within the empty space of the universe.    

     You are probably thinking that this allegory is outlandishly disgusting.  But ancient peoples routinely used outlandishly disgusting myths to relate metaphorical abstract truths.  The abstract truths conveyed by this particular myth are very much in line with evolutionary science.  Consider these points:

     The abortion of the demiurge is a metaphor for how the cosmos was conceived in error; and also that life is born from the sacrifice of juveniles, as natural selection requires, for only if the unfit juveniles are killed before they procreate can survival of the fittest "improve" the gene pool.  Therefore, since survival of the fittest is the governing principle of life, and since it requires the sacrifice of children, it is fitting that the universe is metaphorically called an aborted fetus.  The abortion analogy was apparently also used to incite outrage.  Several ancient writings indicate that the early Christians found the practice of abortion outrageous and wrong.[3]  Jeremiah the Prophet had condemned it in the Old Testament.[4]  Barnabas, Mathetes, and the Didache had condemned it during or shortly after the New Testament period.[5]  Hence, the Gnostics attempted to transfer this feeling of outrage to creation by employing the analogy, in order to compel their creationist opponents to feel outrage and disgust toward the cosmos and toward its creator.

     That the demiurge is blind is a metaphor for how the world is dominated by cruel injustice and random misfortune – for everywhere, car accidents, typhoons, and asteroid collisions destroy the innocent.  It's as if the supposedly Almighty God were a blind Judge with no sense of justice and no ability to perceive right from wrong.  Therefore, the demiurge who created the universe is called Samael, which means "blind god."

     That the demiurge is retarded is a metaphor for how flawed the universe is.  Most of it is either too hot or too cold, or just too full of empty space to support anything living.  If there were any "intelligent design" involved in the creation of this universe, it must have been extremely retarded, for the universe is full of wasted space and material.

     That the demiurge is arrogant is a metaphor for how the universe is pointlessly huge despite being so worthless, for it is grand in size, yet so little of it is useful or inhabitable. 

     That matter was born from Pistis-Sophia, the youngest of the aeons, is a metaphor for ignorance and indiscretion, for in youth there is both ignorance and indiscretion.  Her lack of knowledge and discretion caused her to conceive that which she later decided to abort.  Afterwards, Sophia repented and tried to undo the damage she had done.  Below are some quotes from the historians and Nag Hammadi texts:

Sophia wants to show the cosmos that matter was born from an error named after blind arrogance and stupidity.[6]

The material of the primordial empty universe was flushed out like an aborted fetus.[7]

After they created Adam, they left him for dead, because he was like a miscarriage with no life in it.[8]

She did not have sex, but when she was alone she started touching herself.[9]

Sister Sophia is a whore (because she screwed up when she conceived the cosmos).[10] 

Even the Bible itself adds weight to this, saying, "God thinks the Sophia of this cosmos is stupid."[11] 

     For being such a vulgar and outlandish little fairy tale, the Gnostic creation myth is actually very compatible with science.  Both science and Gnosticism present the universe as an aimless mass of rubbish.  The creator god, the would-be "great architect," is nothing but a blind and arrogant mental retard, and matter is the seeping ooze from his mother's attempt to abort him.  Does this metaphor not fit our universe – so pointlessly filled with nothing but cold dead rock, burning poisonous gas, and worthless empty space?  In these terms, the Christian Gnostics knowingly and willingly committed the most obscene blasphemies against the creator and against all creation, God bless them.  But what they did unknowingly was to prophesy allegorically concerning the true nature of the cosmos before science had discovered it.

     Although they blasphemed all creation, they never blasphemed Christ.  They only blasphemed the god below Christ, which is the demiurge, together with his blundering perverted angels, which are the archons.  It was these who created the cosmos. 

     The Gnostic's success in assaulting the creationist belief system remained unparalleled for almost 1,900 years.  It was not until Darwin that a worthy challenge rose again.  But unlike the secular nature of Darwin's evolutionary science, these Gnostics were rooted in Christianity.  By combining the science of Charles Darwin with the Christian Gnostic theory of origins, we may drive a wedge between Christians and the creationist heresy, thereby producing a synergy with which to nail a stake in the heart of creationism.
