Numbers 13

the people, that we beheld, are of a tall stature. [34] There we saw certain monsters of the sons of Enac, of the giant kind: in comparison of whom, we seemed like locusts.

I’ve read a book and seen on YT alleged giant skeletons up to 15 feet high, with double rows of teeth top and bottom and six fingers/six toes on each hand/foot, extra joints, extra hand and foot bones, extra ribs, extremely high foreheads have been dug up in the USA in the Indian Burial Mounds in the middle of the country. Some slightly smaller of about 8-11 feet tall have been found in the Carolinas, Georgia, Virginia, West Virginia, inside of caves. This was mostly in the 1920’s. Many of them were displayed around the country as entertainment. For a small fee, families could make a day of it. Pay your family nickel or 2c. apiece to see the Biblical Giant’s skeleton and have a family picnic in the park. But then they just sort of disappeared from sight, the media, and memory as the US slid into the Depression.
It is said many of them were donated to universities for study, but no university claims to have ever received such an item or studied one. Many of the skeletons are said to be locked in storage in the basement of the Museum of Natural History in NYC. Others say that’s an urban myth like the alligators living and breeding in NYC sewers. The infamous Scopes Trial about evolution may have played a factor in their sudden disappearance from display and flushing down the memory hole.
It’s interesting, for sure, but what difference does it really make?  Some say they are the Nephilim or the cursed offspring of the Nephilim, the last of whom were wiped out in the Flood of Noah. Maybe the entire thing was a scam, like Piltdown Man. It would be fairly easy to fake such a thing even today. Make a giant skeleton out of plaster or in a 3-D copier. Set it up in a lab. Get some “archeologists” to study it, “carbon date” it, put it online and watch it go viral! But only a select few whom we must believe have ever actually seen it or examined it. It has to be kept in a special freezer at a specific temperature, humidity, and air pressure lest it decay into a puddle of mush. Lots of people would believe it. After all, we moderns “trust the science,” do we not? 
Or maybe not!
Spending too much time on such matters can derail one’s spiritual life, family life, physical health, mental health, financial health…
Whether it’s true or not, “getting it right,” does not get us into Heaven or if we get it wrong, keep us out! Same with the moon landing, shape of the earth, geocentrism, heliocentrism, germs or no germs, nukes or no nukes, knowing who or what exactly happened on 9-11, do not determine our soul’s destiny.
By God’s grace in Heaven, the very smartest of us will find out we knew nothing on earth. We’ll probably find out Adam and Eve even after they fell, were smarter than today’s most advanced tech whizzes, nuclear physicists, polyglots, people with photographic memories, the nine year old boy who aced the State of Florida bar exam on the first try, having graduated high school on his sixth birthday. I’ve no idea what became of him or if he’s still living. If he died, I hope he saved his soul, but if he did, it wasn’t because he became a lawyer at age nine! 
“For I judged not myself to know anything among you, but Jesus Christ, and him crucified.”
[St. Paul 1 Corinthians 2:2]

Related to this topic! So easy to see in the mind's eye what the boy David was up against...I mean " look up...Waaay UP.   I never tire rereading that epic challenge.

And king Saul was also tall (er) (than the rest of men?)

Genesis 6:4  mentions giants...

Great post. I tried to give a "thumbs up" but a message wrongly said I had already voted on that post.

They'd make quite the NBA team 

Seriously, though, one thing that occurs to me, as I look at this, is that the cranial capacity of these giants would have been far greater than that of modern man.  Did they have larger brains, and consequently some of the preconditions for greater intelligence?

If these giants built the Egyptian pyramids, perhaps so.

Probably. But what I don't understand is how we had giants after the flood.

Pre-flood, the giants were abominable creations which involved witchcraft and the occult.  

If you look at the POST-flood history, giants only appear in the satanic, anti-God cultures such as the caananites, philistines, etc.  There’s never been giants in the Israelite community.  They re-arose due to the occult and satanism.
