The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
Many people scoff at this verse in the Bible and say that it is just a myth or a fairy tale. But further research on the story of the Nephilim state that they were very violent and even cannibalistic. The odd thing is, that there are stories from all over the world about these races of giants who attacked native tribes and peoples and carried them away to be eaten. Add to that, the fact that skeletons have been found that stand up to twenty feet tall!!! A little research into this matter will uncover scores of old and new newspaper articles written about archeologists who have discovered these types of remains. Were these ancient giants some kind of unholy hybrid between man and something else?
Many believe that the modern day alien abduction phenomenon is closely related to the story of the Nephilim. The theory is that some interdimensional race of beings has, and still is tampering with the DNA of human beings; and for what reason, can only be speculated. Could these beings be what we call angels and demons? Sounds almost laughable doesn't it? But then think of the fact that some of our leading scientists believe that planet earth could have been seeded by extraterrestrials and that it how life on earth actually began. Now factor in the fact that many scientists have suggested that these extraterrestrials are interdimensional rather than interplanetary. Could it be that that what mankind calls heaven is another dimension? Could it just possibly be that such beings as God, angels and demons are a race of spiritual/energetic beings that never grow old, never decay and possibly could exist for an eternity? After all, energy can't be created or destroyed... as they say. It does make a body wonder. And it should make all of us consider what this means to each of us if there is any truth to the Genesis account. And it should also cause us to look into such matters a little more deeply and find the truth for ourselves. It's a big universe out there, and in the wake of its vastness, we are but a speck of dust in the ocean of time.
