What do we have from scripture, lets look...
Genesis 6:4
There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
Numbers 13:33
And there we saw the giants, the sons of Anak, which come of the giants: and we were in our own sight as grasshoppers, and so we were in their sight.
Deuteronomy 1:28
Whither shall we go up? our brethren have discouraged our heart, saying, The people is greater and taller than we; the cities are great and walled up to heaven; and moreover we have seen the sons of the Anakims there.
Deuteronomy 2:11
Which also were accounted giants, as the Anakims; but the Moabites called them Emims.
Deuteronomy 9:2
A people great and tall, the children of the Anakims, whom thou knowest, and of whom thou hast heard say, Who can stand before the children of Anak!
Joshua 13:12
All the kingdom of Og in Bashan, which reigned in Ashtaroth and in Edrei, who remained of the remnant of the giants: for these did Moses smite, and cast them out.
Joshua 17:15
And Joshua answered them, If thou be a great people, then get thee up to the wood country, and cut down for thyself there in the land of the Perizzites and of the giants, if mount Ephraim be too narrow for thee.
Deuteronomy 3:11
11 For only Og king of Bashan remained of the remnant of giants; behold his bedstead was a bedstead of iron; is it not in Rabbath of the children of Ammon? nine cubits was the length thereof, and four cubits the breadth of it, after the cubit of a man.
1 Samuel 17:4
And there went out a champion out of the camp of the Philistines, named Goliath, of Gath, whose height was six cubits and a span.
We have this from SOP..
"As Adam came forth from the hand of his Creator....He was more than twice as tall as men now living upon the earth....Eve was not quite as tall as Adam. Her head reached a little above his shoulders." (Spiritual Gifts, Vol. III p. 34).
Man was the crowning act of the creation of God, made in the image of God, and designed to be a counterpart of God.... Man is very dear to God, because he was formed in His own image.3The Review and Herald, June 18, 1895.
As Adam came forth from the hand of his Creator he was of noble height and of beautiful symmetry. He was more than twice as tall as men now living upon the earth, and was well proportioned. His features were perfect and beautiful. His complexion was neither white nor sallow, but ruddy, glowing with the rich tint of health. Eve was not quite as tall as Adam. Her head reached a little above his shoulders. She too was noble, perfect in symmetry, and very beautiful.(The Story of Redemption, 21.)
Man came from the hand of God perfect in every faculty of mind and body; in perfect soundness, therefore in perfect health.(Good Health, March 1883)
God endowed man with so great vital force that he has withstood the accumulation of disease brought upon the race in consequence of perverted habits, and has continued for six thousand years....
If Adam, at his creation, had not been endowed with twenty times as much vital force as men now have, the race, with their present habits of living in violation of natural law, would have become extinct.(Testimonies for the Church 3:138, 139.)
Created to be 'the image and glory of God,' Adam and Eve had received endowments not unworthy of their high destiny. Graceful and symmetrical in form, regular and beautiful in feature, their countenances glowing with the tint of health and the light of joy and hope, they bore in outward resemblance the likeness of their Maker.(Education, 20.)
"Adams height was much greater than that of men who now inhabit the earth. Eve was somewhat less in stature;" (Patriarchs and Prophets, p. 45).
So SOP has that Adam was more than twice as tall as men today. Now take a look at this video..
