It is significant that giants are spoken of in this context. They also became "mighty men" and "men of renown". Gigantism is a genetic abnormality, and this too is evident in the description we have of giants in Scripture. The Nephilim and Anakim of the Old Testament were indeed giants,
And every nation on earth has myths and legends about "gods and heroes" such as Hercules, etc. There has to be some reality behind all that, and Scripture simply condenses the truth into a few words. The evil angels taught men all kinds of perversions, and they also produced mighty and abnormal offspring. Those legends descibe these things.
I agree Ezra, this article here https://answersingenesis.org/bible-characters/giants-in-the-old-testament/
paints a fascinating picture of giants in the Bible and in our past. I wholly concur that the legends and stories of giants exist because they actually did exist in our past. This article showed me far more examples than I knew existed in scripture. I find it odd that God would allow fallen angels to mate with woman to make these giants however. Here’s another theory that just struck me when I read this: The underlined red text is key.
SNIP>>>>>As far as I know, no one has discovered fossil evidence of giant humans. But then again, human fossils are quite rare altogether, since humans are more capable of avoiding rapid burial in sediment and other conditions that could lead to fossilization of their remains. What is indeed significant is that many giant versions of other creatures existed in the past or still exist today. To name just a few, these include the following:
1.spiders (e.g., the bird-eating spider, up to 12-inch leg span)
2.moths (e.g., the Atlas moth, with a wing span of 11 inches)
3.centipedes (up to 13 inches long)
4.snails (e.g., the African giant snail, up to 15½ inches long)
5.frogs (e.g. Beelzebufo, 16 inches high)
6.dragonflies (e.g., Meganeura, with a wing span of more than 2½ feet)
7.rats (e.g., Josephoartigasia, with a conservatively estimated body mass of 750 pounds)
8.beavers (e.g., Trogontherium, about 7½ feet long)
9.scorpions (e.g., the sea scorpion Jaekelopterus, estimated at more than 8 feet long)
10.crabs (e.g., the giant spider crab, with a claw span more than 12 feet)
11.armadillos (e.g., Glyptodon, up to 13 feet long)
12.turtles (e.g., Archelon, up to 16 feet long)
13.fish (e.g., Xiphactinus, 19 feet long)
14.sloths (e.g., Megatherium, which stood about 20 feet)
15.worms (e.g., the giant earthworm, up to 22 feet long)
16.sea cows (e.g., Hydrodamalis, 25 feet or more in length)
17.crocodiles (e.g., Sarcosuchus, up to 40 feet long)
18.snakes (e.g., Titanoboa, over 42 feet long)
19.crustaceans (e.g., supergiant amphipods 10 times larger than those previously discovered)
20.squid (e.g., Mesonychoteuthis, 50 feet or more in length)
21.sharks (e.g., Rhincodon, up to 65 feet long)
22.octopuses with 100 foot long tentacles.21
The fact that scientists have discovered animals with body sizes far greater than those observed today suggests, at least in theory, the possibility of there having also been giant humans in the past, as recorded in the Bible.<<<<<<<<<
****Perhaps the old earth atmosphese was condusive on several levels to giant humans just as the animlas where far larger? Just a thought!
