This is in reply to your 2/26 post A GREAT STORY - FOR SURE!!!! (fivedoves.com)  If the Serpent Satan was the tree of knowledge of good and evil, and sex with the Serpent Satan was the forbidden fruit that Eve partook of, then why wasn't the Serpent Satan, a fallen angel, locked up like the other fallen angels who went into women and created the giants? And there is no mention in the Bible of Cain being a giant as a result of a fallen angel Satan having sex with a woman Eve. 

Also since Adam also ate the same forbidden fruit, the same forbidden fruit that Adam partook of wasn't sex with Satan because Eve gave Adam the fruit from the tree of knowledge of good and evil and he ate it.  Adam had sex with Eve which wasn't forbidden because the Lord God told them to be fruitful and multiply (Gen. 1:28).  Genesis 4:1 says, "And Adam knew Eve his wife; and she conceived and bare Cain, and said I have gotten a man from the Lord."  The Bible is the truth and not a lie so Adam knew (really had sex) with Eve his wife; and she conceived and bare Cain making Adam the father of Cain and not the Serpent Satan.  Cain was conceived (Gen. 4:1) after Adam & Eve were driven out of the garden of Eden by the Lord God (Gen. 3:23-24, and not while they were still in the garden of Eden with the Serpent and with the tree of knowledge of good and evil.

In regard to your statement below, there is no difference between in the meaning of the word "tree" and the word "trees" in the Hebrew Concordance as they are both word #6086 as shown at Strong's Hebrew: 6086. עֵץ (ets) -- tree, trees, wood (biblehub.com)   Strong's Hebrew: 6086. עֵץ (ets) -- 329 Occurrences (biblehub.com shows that it is used 329 times. The tree of knowledge of good and evil is in Genesis 2:9 & 2:17. In fact the word "tree" in the tree of life in Gen. 2:9 is spelled exactly the same way as the word "tree" in the tree of knowledge of good and evil in the same verse in Gen. 2:9.  As for the word "atseh," it is Strong's Concordance word #6096 which means "spine" or "backbone" which is used only 1 time in Leviticus 3:9 and it is not used at all in Genesis. It does not mean man.  Please see Strong's Hebrew: 6096. עָצֶה (atseh) -- spine (biblehub.com)

Again there is a separation from the trees “etsin” and the tree “atseh” which dwells in the midst of the garden. The etsin are regular trees. The atseh is a man; in this case, the serpent or Satan.
