Hi

How the giants built is sometimes cryptic.
Nan Madol...2 giants and a dragon

David Flynn should have a youtube- The Giant geoglyphs of tiawanaku.
Its his redice radio int from 2008 if memory serves.

Richard Dewhurst audio int reffed or other resources by him frame the
giants builder capability in America.

My personal opinion is the Elite...or the ruling cast from Mu/Lemuria
and Atlantis had ability beyond sheer size....
That journey is cryptic too as you parse thru mythology or theosophical
society forwards.

This months AOM and the Odyssey has giants prominent.
I found a website with extensive mytholore from Solomon islands on giants
its gruesome.....the cannibalistic story and violence accross this pacific
region finds mirror in the Odyssey of Homer.
If Homer never left the Med....the hint is giants in that region were as ferocious
as Pacifica.....or America.

Still....sufficient mytholore comments that Giants were benevolent...
Protectors of peoples..sages....travelling teachers.

One wonders if the decline of Mu/ Lemuria and Atlantis saw the surviving giants
cultures decline with some turning to organized cannibalism.
This created the hate and vendetta of peoples who genocided them.

The Germannic tribes which faced Roman legions had giants in the 1000's
Many were killed in battle.

Supposedly...the Anunnaki of Sitchin were giant stature.
LLoyd Pye considers intervention theory valid by his DNA research.
Mainstream science points to Desnovian line which went extinct.

If some race of beings visited earth several hundred thousand years ago
Removing resources and doing genetic manipulation
how would we know exactly?
