The very sound of the title: "Return of the Neanderthals", seems like a title that would make a nice Hollywood story: like a modern retake on "Frankenstein" and/or even "The Planet of Apes". I find that we have this theme running in science fictions where human beings create an artificial being that is much stronger than themself who ends up tormenting humanity and becoming an oppressor, with the human creator (or creators) losing control over such beings. This idea is also expressed in Jewish mythology through the idea of the Golem, which in my opinion shows that all our (scientific) thoughts and developments are driven to some extent by our mythologies (more to come on this later).
Of course, the seriousness of the matter is overlooked. Our [mad] scientists who actually try to summon these extinct beings from the dead through cloning, need to be guided by our science fictions that warn us that one day we will create something that will almost devastate us. As they say, the road to hell is paved by good intentions. Hence it is much frightening when we consider the science fiction scenario of how we as human beings create or summon beings into our dimension that will totally devastate, oppress us and lead us to our ruin. Yet, in reality, this is actually being done and has been done in the past. Our pagan religions have sought to communicate to and establish connections with other beings not of our world that have lead to demonic possession and domination by fallen angels. But even if you do not believe in fallen angels and demons, if you just consider our science fictions and what they tell about the dangers of our inventions, it does point out that if man's destiny is in his own hand, then what a frightful and fearful future is on the horizon for us as humanity.
Essentially, human nature cannot be trusted. I have no trust in human nature. Men conspire, scheme, institute tyranny and oppress others. Such nature has not yet changed. And as long as human beings are the same as they were for millenia, then someone will use science and technology for evil. Already, we see that the US military is contemplating creating (Weinberger, 2013) and attempted to create (Heussner, 2009) supersoldiers. However, even if humans do not intend to use their inventions for evil, as our science fiction themes point out, there can be unintended consequences of even creating artificial beings, especially humanoids.
But, since I subscribe to Judeo-Christian eschatology, I know that the future is not as scary as how science fiction predicts that it will be, at least not for everyone. The Bible already tells us how the world will end, thereby telling us that our fate is not in our own hands. However, this latest development could in fact create what we call the return of the Nephilim from Genesis 6:4. This is already an idea that is explored in Harding (2010), who suggests that what the ancients called the Nephilim may actually be the Neanderthals so-called by today's scientists. In addition, Jesus himself did say that the end of the world will be like the time of Noah (Matthew 24:37; Luke 17:26), lending credence to the fact that the Nephilim could actually return. Hence, it is very possible that our scientists in an attempt to bring extinct humanoids back to life, may create and resurrect the Nephilim of the 21st century.
Currently, we have demons, which according to some scholars are the disembodied souls of the Nephilim that continue to roam the earth and look for human bodies to possess and inhabit (Klein & Spears, 2005). As such, I do not see it as farfetched that human scientists are creating the conditions for the return of these demonic entities in physical form that will permit them to regain physical bodies to oppress us as they once did before the flood. In fact, the imagery in the book of Revelations does show one such possibility. In one chapter of Revelations, the Bible speaks of an image being created, who will kill all that do not worship it (Revelation 13:15). When we consider that there is to be a seed of the serpent (Genesis 3:15), it is clear that Satanic forces are driving our science to create a body in which Satan can find an incarnation, just like how Jesus was an incarnation of God (an idea I know that many currently do not accept). Biblically, it makes sense.
