Then God said, “Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, each according to its kind”; and it was so. And God made the beast of the earth according to its kind, cattle according to its kind, and everything that creeps on the earth according to its kind. And God saw that it was good.

So when God made the earth, he only wanted each species breeding within it's own kind (i.e., dogs with the same or other species of dogs, humans with the same or other races of humans, etc). He did not want cross breeding, i.e., a humans breeding with dogs.

the Angels saw the daughters of men were beautiful; and they took wives for themselves of all whom they chose. There were giants (Nephilim) on the earth in those days, and also afterward, when the sons of God (fallen angels) came in to the daughters of men and they bore children to them. Those were the mighty men who were of old, men of renown.

Angels cannot die, and therefore had no need of breeding. However, they seem to have DNA like humans, and seem to know how to mix their DNA with human DNA. They came down from heaven and mated with human females (it is unclear how, but it is possible they had some kind of insemination technology available), producing unnatural hybrid offspring whose DNA was neither human nor angelic. These offspring are what the various ancient cultures worshiped as gods (the various hindu gods like shiva and vishnu, the gods of greek mythology like Apollo, etc).

So God looked upon the earth, and indeed it was corrupt; for all flesh had corrupted their way on the earth.

God wasn't happy about Angelkind mixing with humankind, producing offspring whose DNA was neither human nor angelic. The fallen angels (Azazel, etc) were immediately condemned to the bottomless pit for their sin without a path for redemption, but God offered humans a path for redemption through Noah, and ultimately, His begotten son, Yeshua. The hybrid offspring of these fallen angles became the demons that still roam the earth. But note that at this point, it was only angels mating (presumably forcibly) with humans.

Now the two angels came to Sodom in the evening, and Lot was sitting in the gate ... he rose to meet them, and he bowed himself with his face toward the ground. ... they turned in to him and entered his house. ... The men of Sodom, both old and young ... called to Lot and said to him, “Where are the men who came to you tonight? Bring them out to us that we may know them carnally.”

Lot greets the angels visiting his town by bowing down before them, so there must have been something that visually identified to him that these "men" were Angels, and not merely human. If Lot could tell they were angels, then presumably everyone else in the town could identify them as angels as well. We all know homosexuality, and likely pedophilia, was rampant in Sodom and Gomorrah. But what's interesting here is that the men specifically wanted to have sex with the angelic visitors to Lot's house.

Lot went out to them ... and said “Please ... do not do so wickedly! ... I have two daughters who have not known a man; please, let me bring them out to you, and you may do to them as you wish; only do nothing to these men, since this is the reason they have come under the shadow of my roof.” And they said, “Stand back!”...

So Lot offers them his (presumably early teen and) virgin daughters, but the men insist on having sex with Angels. So we've come to the point now where it isn't just fallen angels mating with humans, but humans wanting and willing to mate with angels. This must have been going on for a while for all men in the town to come hammer on Lot's door for some "fresh meat".

But as the days of Noah were, so also will the coming of the Son of Man be.

Jesus tells us that in the last days, these demons will mate to produce physical, hybrid offspring again.

What if all the alien stories we increasingly hear these days are really these demons masquerading as "aliens", and extracting human DNA to produce hybrid offspring (which they will reveal soon, or perhaps creatures like Bidet, Turdo, and the rest of the cabal / elite are already hybrids)? And what if the whole gay / trans / pedo agenda is simply a stepping stone to get people accustomed to having sex with these hybrid creatures, producing more hybrid offspring, to the point where all flesh is corrupt again?

So God created man in His own image; in the image of God He created him; male and female He created them.

Then out of the smoke locusts came upon the earth. They were commanded to harm only those men who do not have the seal of God on their foreheads. In those days men will seek death and will not find it; they will desire to die, and death will flee from them.

He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name.

Is "not having the seal of God" the same as "receiving the mark of the beast", which is nothing more than human DNA mixed with demon / satanic DNA? The result would be something that has a human body but cannot die, and is tormented in hell forever, with the devil and his fallen angels (demons).

Are the covid vaccines technology that makes humans more receptive to this alien DNA? Or perhaps they are sterilizing agents that will cause human reproduction to crater and become a thing of the past, leaving mating with aliens or dying out as the only viable options.
