I know very little about this topic, yet something tells me it merits further investigation. We know from scripture that there were giants. Enoch speaks of the Nephilim, Deuteronomy speaks of the Anak-im.
I believe Goliath/Anak (Anakim?) are descended from such life-forms as well (6 fingers isn't quite human).
If there were giants, it's possible there were also giant trees. There are Native American legends of giants running across the plains scooping up buffalo and devouring them as they ran (if stories be true). The idea of scooping up a 1,500 lb. bovine animal under your arms seems far-fetched in the extreme (having never seen one myself), however, my curiosity exists.
Thanks to the OP for sharing this topic!
I found this web page very interesting. Perhaps you will as well?

Again there was war at Gath, where there was a man of great stature who had
twenty-four fingers and toes, six fingers on each hand and six toes on each foot; and he also was descended from the giants.
This leads to a further question,
if the flood destroyed all life, where did these giants/hybrids come from? Was the flood world-wide or localized?
Genesis 6:17
"Behold, I, even I am bringing the flood of water upon the earth, to
destroy all flesh in which is the breath of life, from under heaven; everything that is on the earth shall perish.
Peace.
