I was going through Genesis and a though suddenly crossed my mind. The Bible describes the fruit eating process in a way that suggests the height of Adam and Eve was four times the height the men of today.
From general knowledge is that the fruits of most trees are usually located at the top most apex of the tree, for example a mango tree which is mature might measure around more than 10 metres. Now if we assume the tree that Adam and Eve ate from were of the same height as the Mango tree and also the fruits being on top of the tree then if Adam was able to reach and pluck without climbing, then the impression of a giant is created.
**Second Proof that they were giants**
I want you to look at the time God allowed the pre flood generations to live on earth. Adam himself lived on earth for more than 800 years, in modern day that's a whole millenium, Adam was created a mature man, he was never an infant, only to God lol. Now lets take a look at Methuselah who lived for 969 years, Methuselah's case is different because he was born and was an infant. Do you want to tell me that someone will grow from being an infant and age at 969 years at the height of the men of today? I don't think so.
The more years they lived, so did they grow and grow because they were eating so they were simply giants.
After men sinned and God pained in his soul that his spirit will not remain in man for more than 120 years, then the life span of a human being was reduced and so did the height.
Because before the youth of a generation that came directly from Adam would begin at 200 years as a minimum for the case of Methuselah.
Adam was never going to fight dragons and dinosaurs with the stature of the men of today, he simply was a giant to equal a potential threat to the dinosaurs and dragons.
how we got short with time?
The curse before Noah's floods that his spirit was not going to remain with us longer
