Oh boy!

I'll try just once more and then I'm finished here. You are entitled to believe whatever you want about these passages. Being honestly wrong is OK, really.

What no one is entitled to do is to change the Bible to prevent people from coming to a legitimate conclusion. That is what the JWs do. By turning singulars into plurals, the NIV translators have done just that. It no doubt brings pleasure and delight to extreme feminists, and to transgenderists who like to be referred to as 'they,' but it prevents the Christian from finding Christ in all the Scriptures, which is what we are supposed to do (John 5:37; Luke 24:27).
Brother, I am NOT saying I am right here, as I am very open to correction.
Now, let’s look at the NKJV rendering of Psalm 8:4-9...
4) What is man that You are mindful of him, And the son of man that You visit him?
The subject of this verse is ‘What is man that You are mindful of him’. Notice that they capitalized You when it was referencing God? Yet, son of man in the same verse wasn’t? In other places where Son of man was referencing the Christ, Son was capitalized. So the NKJV saw it referencing man, not the Christ. I will expound further. Man is the subject in view.
5 For You have made him a little lower than the angels, And You have crowned him with glory and honor.
6 You have made him to have dominion over the works of Your hands; You have put all things under his feet,
7 All sheep and oxen-- Even the beasts of the field,
8The birds of the air, And the fish of the sea That pass through the paths of the seas.
Now, who is the ‘him’ being referenced in these verses? Man who has been given dominion over sheep and oxen, beasts of the field, birds of the air, and the fish of the sea. God gave this dominion to Adam and all his posterity when He said to him,
”Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth."[Genesis 1:28]
9 O Lord, our Lord, How excellent is Your name in all the earth!
Then we see the Psalmist praising God for what He has done.
