Ancient Giant Petrified Tree Stumps Around The World - Giant Skeletons

The angels cut down the trees and YHVH preserved them, just before the flood.
Enoch.
Daniel 4

19Then Daniel, whose name was Belteshazzar, was astonied for one hour, and his thoughts troubled him. The king spake, and said, Belteshazzar, let not the dream, or the interpretation thereof, trouble thee. Belteshazzar answered and said, My lord, the dream be to them that hate thee, and the interpretation thereof to thine enemies.

20The tree that thou sawest, which grew, and was strong, whose height reached unto the heaven, and the sight thereof to all the earth; 21Whose leaves were fair, and the fruit thereof much, and in it was meat for all; under which the beasts of the field dwelt, and upon whose branches the fowls of the heaven had their habitation: 22It is thou, O king, that art grown and become strong: for thy greatness is grown, and reacheth unto heaven, and thy dominion to the end of the earth.

23And whereas the king saw a watcher and an holy one coming down from heaven, and saying, Hew the tree down, and destroy it; yet leave the stump of the roots thereof in the earth, even with a band of iron and brass, in the tender grass of the field; and let it be wet with the dew of heaven, and let his portion be with the beasts of the field, till seven times pass over him;

Enoch

Chapter 66

1In those days the word of God came to me, and said, Noah, behold, your lot has ascended up to me, a lot void of crime, a lot beloved and upright.
2Now then shall the angels labour at the trees; but when they proceed to this, I will put my hand upon it, and preserve it.
