So, you have a deity and you think that deity exists and that your religious book is the word of that deity.
OK. Taking that as a given for a moment, but only for a moment, I have a slightly different question;
* Where did your deity ever say that it was good?
As I pointed out, the quotes you gave from your religious text, Genesis, do not say that your deity says it is good. Instead, they say your deity was able to identify something that was good.
If you do not know the answer to this question, and you are only saying you believe your deity to be good, then state that. It will be an acknowledgement of the validity of my question, but that new statement will be one that you can support for what it is without digging a hole for yourself.
Where did my God ever say it was good? What are you referring to by “it” in your sentence? Himself? So where did God ever say He, Himself is good?
If that is what you are referring to, then I must respond that the entire Bible is full of passages declaring God is good.
Again, God inspired the words that are written in the Bible to be exactly what He wanted them to be. This was His way of explaining and describing who He is. So the fact that quotes like this are found in the Bible clearly inform us God is good . . .
He is the Rock, his works are perfect, and all his ways are just. A faithful God who does no wrong, upright and just is he. – Deuteronomy 32:4
Be perfect, therefore, as your heavenly Father is perfect. –Matthew 5:48
for it is written: "Be holy, because I am holy." – 1 Peter 1:16
This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. –John 1:5
To declare that the LORD is upright; He is my rock, and there is no unrighteousness in Him. –Psalm 92:15
Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows. –James 1:17
But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. –James 3:17
For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil." –Genesis 3:5
As for God, his way is perfect; the word of the LORD is flawless. He is a shield for all who take refuge in him. –2 Samuel 22:31
"As for you, you meant evil against me, but God meant it for good in order to bring about this present result, to preserve many people alive. – Romans 12:2
Whoever invokes a blessing in the land will do so by the God of truth; he who takes an oath in the land will swear by the God of truth. For the past troubles will be forgotten and hidden from my eyes. – Isaiah 65:16
Into Your hand I commit my spirit; You have ransomed me, O LORD, God of truth. – Psalm 31:5
All of these passages – (though certainly not all there ar) reveal that God was communicating with us that He is Good. This is clearly what He wants us to realize. And based on His actions, behavior, words, divine nature, supreme beingness, etc, it is most definitely something we can conclude to be true.
Scripture is what God thinks and what god says, therefore there is no other conclusion then to know God is good.
“Scripture is the word and mind of God, and just as it is a contradiction to say that we love a person and hate everything about him (since everything about him is him), our iove, faith and reverence toward God can never rise higher than our love, faith, and reverence toward the Bible.” www.vincentcheung.com
14 But as for you, continue in what you have learned and have firmly believed, knowing from whom  you learned it 15 and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. 16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God  may be competent, equipped for every good work. -- 2 Timothy 3:14-17
