Five talents equals one nephilim. Ha.
It's also worth noting that there were 2 cubits: a common cubit (18") and a royal cubit (21"). Other nations had their own cubit standards that were not calibrated to the Egyptian standard, and also had the common/royal distinction. So it's important in an article mentioning cubits to specify which cubit was in use.
You are correct that the descriptions we get widely vary. From what I understand, the definition of a talent depended upon the time and place it was being spoken of. From the Catholic Bible Dictionary:
TALENT An ancient unit of weight and value, normally that of metals such as silver and gold. The Hebrew talent (kikkar) was about 757 pounds or 35 kilograms (1 Kgs 9:14; 20:39).
The Greek talent (talanton) was also a large amount of money, but the unit varied greatly depending on the time, place, and metal (Matt 18:24; 25:15-18) 18:24; 25:15-18).
Skeletal remains ?
They find bones of giants, the Smithsonian comes in, and you never see it again.
They were metric cubits..,,
I need to adjust my glasses. I read Epstein scroll. 🙄🤪
I will just leave this right here: There is a giant in Kandahar, Afghanistan. No one wants to talk about. It ate humans. Our military knows about it.
I used to have a good old book WORD KEYS WHICH UNLOCK SCRIPTURE. In it, the definition of a “giant” was “Mighty Men of Stature” or warriors considered the equivalent of “demi-gods” by the ancients.
You will find many of them in the Iliad.
They could have rolled out a blank scroll and traced the outline of one of the '4 to 5 cubit' tall individuals.

Sounds like a tall tale.

Yes—those guys are great counter‑examples to any claim that extreme height is automatically non‑functional.
Gheorghe Mureșan reached 7′7″ because of a pituitary disorder (gigantism/acromegaly), yet still played several seasons in the NBA and needed tumor treatment primarily for long‑term health risk, not because walking was impossible.scholar.lib.vt+2
Sun Mingming at 7′9″ likewise had acromegaly from a pituitary tumor, but after surgeries he was able to train for hours per day and play professional basketball, even if his size imposed extra strain and medical issues.latimes+2
Olivier Rioux, currently listed around 7′9″ and ~305 lb, was tall from early childhood and is playing high‑level organized basketball as a redshirted college center, which suggests at least some tall individuals can be highly active without obvious crippling disability.wikipedia+1
So: human biology clearly allows rare, functioning individuals close to 8 feet tall. That supports your main point: the fact that something is statistically extreme does not mean it is biologically impossible or necessarily non‑functional, and it leaves the door open—at least in principle—for a rare, very tall warrior or champion figure in antiquity.
