Were these really giants, or have we just been getting shorter & shorter?

IMO 2nd one.

Aloha
When I was in the 5th grade one of the students was the same size as my dad 6' tall 180 lbs
He stood out among all of us.
HE wore adult clothing
So he must have had the giant bloodline gene ?

Something in DNA (awakened?)

if giants/nephiliam are bad, then Tartaria is bad? something im missing here

Was just gonna write that was told, all these anomalies were the result of demons procreating with human women.

From what I've read, pre-flood people and animals were giant size; there was a greater oxygen level to support their size. For example, fossils of dragonflies with three foot wingspans have been found. That was also the time of the giant trees, which would have produced an incredible amount of oxygen. According to the book of Enoch, before the flood angels cut down the massive trees. The stumps of those trees can be seen all over the world, one of which is Devil's Tower (photo below); the stump is over 800 ft high.

The actual nephilim had six fingers on each hand and six toes on each foot. Latent genes can be seen in some people today (check "celebrities with six toes").

Some research points to the Tartaria era being the millennial reign of Christ (architectural perfection, dates on buildings changed in our era & timeline altered, giant doors indicate size of people during that era).

Much that has been hidden is coming to light now.
