Giants

There were giants on the earth in those days; and also after, when the sons of God came in unto the daughters of men, and then bare children to them, the same became mighty which were the heroes of old, men of renown. – Genesis 6:4

The Bible mentions Giants 25 plus times in the bible. We all know the story of David & Goliath.  Another story is the story of the spies of Mozes. They agreed that the land was good with plenty to offer, but ten of the spies also were fearful that Israel could not take the land because of the people living in it: “The land we explored devours those living in it. All the people we saw there are of great size. We saw the Nephilim there (the descendants of Anak come from the Nephilim). We seemed like grasshoppers in our own eyes, and we looked the same to them” 

It may seem that the flood wiped out all wickedness, thus removing the Nephilim from the earth. But as scripture states in Genesis 6:4

The Nephilim were on the earth in those days—and also afterward—when the sons of God went in to the daughters of humans, who bore children to them. These were the heroes that were of old, warriors of renown.

It seems they survived somehow. At least the offspring... There are too many Bible stories about giants to dismiss them all. The Original "Nephilim" might be destroyed, but their offspring is mentioned numerous times in the Bible.

Nephilim

If you've read the Ancient Knowlegde, you will stumble upon the story of Enoch. This story explains how the Fallen Angels were cast out of heaven and made children (Nephilim) with the daughters of men. The book of Enoch gives is more insight in these creatures.

We read in The book of Enoch :

Chapter 7.

And they became pregnant, and they bare great giants, whose height was three thousand ells Who consumed all the acquisitions of men. And when men could no longer sustain them, the giants turned against them and devoured mankind. And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another’s flesh, and drink the blood. Then the earth laid accusation against the lawless ones.

3000 ells ? *, 1 ell is about 0.30 meter so these Giants were indeed Giants their length was about 900 meters, the Greek translation speaks of 300 cubits (1 cubit is 0,45 meter) so even in the Greek tradition these Giants had the respectable length of 135 meters.

* here is mentioned the "old" ell which is about 0,3 meter.

This is not the only place where is spoken of their enormous length,. In most Myths, Legends and Sages it speaks of Giants with a length of about 6 to 90 meters. (Cyclops with one eye was one of these Giants but there were many more). In verse 5 we read a dazzling story that the "Nephilim" began to sin against birds, beasts and reptiles and even they began to eat their flesh and drink their blood. Reading this story makes it more understandable what is written in Legends and Myths where is told that the most "strange" beings once existed on Earth.

One of the first stories we find about these Gods, Demi Gods, Demons and Monsters we can find in Mesopotamia, in the Sumerian, Acadian and Babylonian stories regarding the Anunnaki, Igigi and Sebitti.
