Cryptozoology is a pseudoscience and subculture that searches for and studies unknown, legendary, or extinct animals whose present existence is disputed or unsubstantiated however I believe this explanation may be a good indication of how cryptids came about. We start with the Nephilim being on the Earth pre-Great Flood and post-Flood.
Genesis 6:4, KJV: There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
In my opinion, it is the Nephilims reappearance after the Great Flood as to why today's cryptids exist.
The Nephilim reappear in Numbers 13:32-33
King James Version
32 And they brought up an evil report of the land which they had searched unto the children of Israel, saying, The land, through which we have gone to search it, is a land that eateth up the inhabitants thereof; and all the people that we saw in it are men of great stature.
33 And there we saw the giants, the sons of Anak, which come of the giants: and we were in our sight as grasshoppers, and so we were in their sight.
Nephilim not only practised cannibalism but also bestiality that is why God ordered the destruction of everything that breathes including animals in the lands of Canaan. To understand the reasons why I believe the cryptids evolved from this activity we must read below no matter how unsavoury it is. Here is an excerpt and as I said very unsavoury.
There should be no surprise that bestiality would occur for the Canaanites since the god they worshipped practised it. From the Canaanite epic poem, The Baal Cycle we learn:
Mightiest Baal hears; He makes love with a heifer in the outback, A cow in the field of Death’s Realm.
He lies with her seventy times seven, Mounts eighty times eight; [She conceiv]es and bears a boy.

The Nephilim had supernatural DNA and who knows what other monsters they created? and I believe it comes to us in the form of modern-day cryptids.
All of this activity falls within the realms of the dark side of evil the Bible tells us in Ephesians 5:11, KJV: And have no fellowship with the unfruitful works of darkness, but rather reprove them.
Respect the power of the dark world and don't play around with it it can open portals to the evil world and this is where these entities come from.
If you openly seek these creatures Bigfoot, Dogman you will have an encounter be it not a positive one.
These entities are with us today I believe as a result of Nephilim corruption and they have an end-time intention.
I have mentioned these two passages from the Bible on more than one occasion but I'll say it again:
Revelation 6:8, KJV: And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
IMO these are the beasts of the earth that Revelation 6:8 is referring to. When God removes his Hand from the Earth in the end days these creatures will be unleashed upon mankind that is why they are being restrained at present. Bigfoot and Dogman exist in every continent on Earth except Antarctica and their numbers are increasing and becoming more emboldened if wild beasts mean lions, tigers, and all animals that are a danger to man then these animals only exist for a couple of continents and many of these beasts are fast becoming an endangered species.
Leviticus 26:22 - KJV - New King James: I will also send wild beasts among you, which shall rob you of your children, destroy your livestock, and make you few; in number and your highways shall be desolate.
Bigfoot in America in the early colonisation period were well known to abduct women and particularly children from Native American tribes. Even today they have been observed with a morbid fascination of children.
I reiterate this is only my belief in cryptid origins.
