one of my theories

It may assist in your thinking here if you take your idea of "spirits" and "entities" and merge them with your idea of "aliens" somewhat. Really, there are only two types/modes of entities: physical and non-physical; those residing directly within the time-space illusion, and those living outside of it in non-physical energy systems. Many of these non-human entities are so skilled in the manipulation of matter and energy that they can move around freely from one density, or level, to another. So, what we really consider "aliens" and "higher dimensional entities" are actually the same thing in many cases.

There have been many times in human history, which--by the way--is MUCH longer than is generally accepted (hundreds of thousands of years at least), where our genetic template has been altered or mixed with that of another, non-terrestrial species. I have been thinking about this subject quite a bit recently. When you take a step back from what has been traditionally taught about evolution, i.e. that it is a wholly natural process, and look at the world and how we humans fit into it, it really is quite amazing that we could even begin to believe that the present human physical body merely evolved from apes through a natural sequence of events.

For instance, and here is a good question to ask of any avid fan of purely Darwinian evolution: why aren't human beings still covered in fur? The process of evolution, while almost infinitely slow, is supposed to effect design changes that make a species better suited for survival within the predatory natural world. So, if that is the case, why aren't humans still covered in fur? Apes most certainly still are, as are pretty much all other mammals, and we are descended from them--aren't we? It certainly isn't the case that we don't need fur any more; in fact we had to take to wearing the fur of other animals until the modern age of fabric and textile use. I only ask because winter is on the way again, and I get really sick and tired of bundling up in layers and layers of clothes to stop from freezing my ass off when I walk outside. A naturally existing layer of fur would have been so much more convenient. I might not look as pretty (hah!), but I'm tired of being envious of the damned dog. My point here being that humans, as we exist now, are ourselves aliens to the natural life system operating upon this planet. The evidence for this being the case is literally staring us in the face every time we look in the mirror. Strange that most people don't ever really notice this.

Very true. If humanity had been left to fend for itself, subject only to the speed of a natural evolutionary cycle, we'd still be building fires to keep our caves warm, and throwing rocks at passing animals in order to have something for dinner that night. The force of evolution is very slow indeed, and probably so for a damned good reason. The fact that this natural cycle has been tampered with so many times here is what makes it such an interesting place to be, however. Still, let us not forget that some of this misuse of technology is only coming about because we are still being interfered with by outside influences.

This is probably not the case, actually. It appears more evident that mankind, long ago, had a much more holistic view of the cosmos and of his spiritual relationship with it than he does now (which is still preserved in some cultures.) Organized religious institutions are a more recent development. Again it is those outside (negative) influences that have largely messed things up here. The name of the game with those guys is: control, control, control.

According to Ret. Col. Philip J. Corso, in his book "The Day After Roswell", this is indeed the case. Some think he was presenting disinformation, however.

Yeah, you can thank Microsoft and AOL for that one: Microsoft for making an operating system that any idiot can use and hack into, and AOL for introducing every type of immature idiot and pervert to the endless possibilities of the World Wide Web. One of the biggest problems we face though is not just our use or misuse of technology, but of our increasing dependence on it. I think that we have become addicted to technology for it's own sake, and this is severely retarding our intellectual and spiritual development. One need only enter any chat room on AOL, MSN, Yahoo, etc, to see that this is clearly the case. Although I personally love technology, I think it is making most people stupid. Today's teenagers are all technology addicts. Every teenage male that I know of is addicted to playing violent war simulation games on their computer for hours at a time. Forget the huge amount of empowering information available on the web; who needs that when you can enjoy blowing your friend's virtual head off with a bazooka over and over again?!

Where and when will it all end? :-/
