Adam was a son of God
by Mark V. Markov

Christ said they will not marry but will be like angels. see Matthew 22:30

So saints will be like angels
Exactly as Enoch's vision

Read Job where it says when sons of God shouted
While God created heaven foundations see Job 38

People did not exist back then
Since earth was created first 
Then all living creatures (animals, birds,fish, etc)
Before Adam and Eve see Genesis chapter 1

Yet still Adam was a son of God
Since God gave him breath
And formed him from nothing except dust ground

He was made first and in God's image
(meaning God is a He and not a she)
Then animals were brought to him
Then only later Eve was formed from his rib see Genesis 1 and 2

So sons of God were as Adam since he was a son of God
Yet women are daughters of Men
Since Eve came from Adam's rib

After he named all animals
And couldn't find a helper
Even though God gave her breath also
Yet he formed her out of a a Man's flesh
Which was Adam's rib. See Genesis chapter 2

So yes sons of God are men 
And sons of God are angels
Except when in Genesis it says sons of God
It means Adam's descendants 
Since he was a son of God

Genesis 6 was before the flood, 
A continuation of Adams descendants who were Men since he was a Man
And therefore sons of God since he was a son of God 
Made in the image of God
Placed in charge of Eden
While Eve was his helper
See Luke 3:38
Genesis 5:1-3
Genesis  Chapters 1 and 2
