If you’re a Christian who really understands what you’re reading in the Bible (or you at least lend a decent amount of credence to the Bible as being a historically accurate set of documents), then it makes sense 100%… Genesis is clear on this. Satan, from the very beginning, has attempted to pollute the human genome. There are two primary motivations for this. 1) any being that is not 100% human (IE, a hybrid of some sort) does not qualify for redemption. God wishes *all* humans to be saved. Satan’s wishes are always 100% opposite of God’s. 2) this is not relevant *now*, but before Christ came to the earth, satan’s gameplan was to pollute (hybridize) the human genome extensively enough that Jesus couldn’t be born of a human..the idea being that there would be no 100% humans left to birth him. Had Christ been born to a hybrid and then be offered up as a sacrifice, *the sacrifice wouldn’t have counted towards redemption of God’s image bearers (humans). Number 2 above is explained fairly well, starting in Genesis 6, through the story of the flood, and even after in later books (both old and New Testament). The flood itself was God’s answer to satan’s plan. “All flesh was corrupted” *except for Noah and his family: a total of 8 100% human people left on the planet at that point in time.* We know that giants existed, and they were the enforcers (and results) of satan’s battle strategy in this regard. That much is covered in the Bible. What’s not explicitly covered in the Bible, but I suspect is true, is that there were various types of hybrids who, along with giants, did not qualify for redemption. So for example, dinosaurs (satan’s attempt to get off of his belly in the physical sense after the curse placed upon him early in Genesis). I’ve heard some teaching from men who I consider to be strong Christians who say this, among other things..such as that the old Greek myths about centaurs and the like were actually based on truth…with the centaurs being - you guessed it - the unholy offspring of human and animal genes. I know it sounds wild, but if you really dig into it and understand the motivations and satan’s strategy at large, it makes perfect sense. This has also been used as a means to explain what demons are and where they came from…demon spirits are the spirits of such hybrids which were wiped out in the flood or otherwise. Because they are not exactly human, they don’t qualify for heaven or hell at this moment in time. Hence why the demons in the New Testament asked Christ “have you come to torment us before the appointed time?” They know that their ultimate destination is the lake of fire. In the meantime, they wander the earth, are territorial, have personalities, have their own desires, and are possessive. Imagine still retaining your senses and being “alive”, but not being able to satiate your desires because you no longer have a physical body of your own through which to satiate them… It’s the reason why they seek embodiment and are always trying to use humans to fulfill their own desires..it’s the only way they can. And there is literally nothing else for them to do. If you knew you had a limited time and where you were ultimately going, what would you do except to get a buzz or a high as often as possible? Or have as many orgasms as you can? Or do whatever else you did to bring yourself pleasure when you had a physical body? All of that said, I don’t believe that taking an injection will turn you into a chimera/hybrid because you’re already born human..though hey, I could be wrong..who knows what sort of sick technology they’ve developed at this point? But at the least, I’d be wary of such things because it may mean that your progeny won’t be 100% human..you’d be in a situation much like the human parents of the giants/hybrids in the Bible…the parents were human, but their kids weren’t. And if all (or most) of the kids aren’t human, then what do you think they produce when they do reproduce? Whatever it is, it wouldn’t be human, either…and thus, not eligible for redemption and essentially a “demon spirit.”
