First of all, the fact must be established that the Greys truly are clones.
This is not a new theory, simply a modification of others that have been circulating for a while. There are several reasons why they appear to be clones, if one takes into account behavioral patterns and visual appearances, as deduced from abductee testimonies and other related reports.
However, the most intriguing evidence is their abduction plans themselves, and not merely second- and third-hand reports from semi-reliable witnesses about ‘tanks of human and alien body parts’ somewhere in the deserts of New Mexico.
The Greys are abducting human males and females for the purposes of extracting sperm, ova, and other samples of our genetic sequences for reasons unknown. There does appear to be an answer as to why they do so, if the relevant data is taken into consideration, as the reader shall soon see.
The Greys must be clones, and the best evidence is in the conduct of the abductions.
One can extrapolate from the Heisenburg Uncertainty Principle (which refers to quantum mechanics and the uncertainty of the location and momentum of an electron in an orbital) that genetic sequences break down and begin to have errors in the sequence after several generations of continuous cloning from clones, which is what many believe is occurring with the Greys.
The result of cloning from clones, after several generation, is equivalent to inbreeding, where errors creep up in the code, so to speak, and eventually, clones are created that are unable to function, i.e., stillborn. This phenomenon is also likened to the recording of a audio or video cassette from another recording. As copies are made from copies, the overall quality decreases.
This postulate can be extrapolated from the fact that the human DNA chain is very long, and contains much data.
If the Greys have a similar genetic code, this hypothesis will still stand. Humans have great genetic variation, and mutations from one generation to the next increase the diversity. However, the mutations that are created generally don’t involve the function of major systems of the body.
Sexual reproduction is also a buffer to radical mutations affecting the entire body in drastic ways from the norm. With clones, however, the mutations, while small individually, will be copied from one generation to another, and as the number of mutations build up, the greater the chance of a fatal mutation.
The sheer complexity of the DNA molecule (in humans) makes it exceedingly difficult to keep tract of every bit of genetic code, and so errors will slip past investigations.
There is another problem in this situation:
While the Greys seem to be able to successfully cross-breed their genetic material with that of Terran humans, their actual knowledge of truly advanced genetic engineering concepts seems to be lacking.
They are not able to manipulate their (or human) genetic code beyond that necessary for the mixing of the two type of replicating molecules. This implied that they either lost the knowledge somehow, or never had it in the first place.
Either way, it appears what the Greys don’t have very much control over the genetic code of the hybrid created.
Thus, cloning from clones creates a dilemma that is fatal to a species dependent on cloning as a method of survival. The way that they propagate is also the method of their death as a species.
However, it may be possible, with the genetic engineering techniques that the Greys seem to possess, to infuse viable DNA or other genetic material, suitably modified, into their own next generation of clones, thus creating hybrids and others much like those often reported by abductees.
While some may say that if they have the technology to do all that, why not create the genetic materials they need and repair their genetic code themselves without resorting to abducting humans?
The answer is very simple, and is a matter of economics: It is by far cheaper, energy- wise and time-wise, to ‘harvest’ the DNA needed, rather that create the genetic materials themselves.
Why spend energy and time building factories, setting codes of purity, as well as finding a source of raw materials for the creation of the replicating molecule, and then reconstructing an entire, functional molecule, when there is a planet of six billion humans which do the job themselves, naturally?
The strategic location of underground bases could make this far more economically advantageous, but even a civilization that is FTL-capable, traveling from a distant star, would save time and energy as opposed to massive efforts create a replicating molecule from scratch.
Thus, this theory would not only explain current abductions, but also past visitations as well, due to the premise that the abductions are for the purposes of harvesting DNA and other genetic materials for infusion into their own genetic code.
One possible explanation is that the Greys do not do the genetic engineering themselves, but that the system is completely automated, with or without a supervisor. In this manner, the genetic engineering involved in combining both types of genetic code would be contained in a computer of some type, and would create a hybrid embryo from human ova or sperm, with the addition of Grey genetic material suitably modified to be compatible with Terran DNA.
One possible method, which would explain the taking of both sperm and ova, would be the following scenario: The ova are modified only very slightly, to make sure of no compatibility problems with the new set of genetic code.
The DNA from the human sperm is then removed, and replaced with the Grey genetic material modified to interact accordingly. The sperm is then allowed to combine with the ova, ‘mixing’ the two gene patterns, and if the code is viable, the resultant embryo grows and divides.
At a certain time, the embryo would be put into stasis, by freezing or by another means, for storage, and implanted into a human female mother for further development whenever convenient.
This scenario would circumvent the apparent ‘hole’ in the theory, and would explain why the Greys seem to have advanced genetic engineering technology at their disposal, yet be unable to repair errors in their genetic code, nor diversify their own code through such manipulation.
They have either lost the knowledge sometime in the past, or simply used the knowledge that another civilization gave them, without understanding what exactly was going on.
