I beg to differ.
One thing is to have a few dozen (hundreds?) skeleton all around 8 ft. tall, which is to mean "there actually was a race that tall".
Another is to say "there was a race with double rows of teeth".
Nobody would believe that, not then, not now.
To say "a specific race has a double row of teeth" is like to say "Tibetans can see in the dark and the Eskimos can breathe underwater".
In other words, scientifically not credible. Unless it was a freak, i.e. a one-off.
Europe is chock full of ancient city walls built with such huge stone blocks, you'd need a modern pier crane to lift them.
Yet they date back to before 1000 B.C.
Kinda hard to hide that kind of evidence, but they're not freaks, it's just the way cities were built way back in the days.
And maybe those guys
were 8 ft. tall.
But nobody had double rows of teeth.
We found bite marks in their cheese...
