God created rest. He didn't simply rest; God is eternal all encompassing and capable of everything and anything. "Sabbath was made for man, not man for the Sabbath" (Mark 2:27)

Here, God literally created rest.

REST DEFINITION: cease work or movement in order to relax, refresh oneself, or recover strength.

The entirety of the cosmos and everything in it seen or unseen was completed by God at the completion of a literal 24 hour day on day 6

As God created, at the completion of a step, He would then proclaim His created as "good".

At the completion of CreaTION, He EXCLAIMED what He had made as VERY (❗️) good 

He had a perfect unadulterated creation. It was in its purest form. God is absolute holiness, purity, and perfection. For GOD to exclaim is to understand that GOD was approved; pleased. The magnitude of this verse is astounding.

All we have known for thousands of years as the humans He created in Genesis is a fallen world and a God who is invisible and at times feels or has to be distant due to our own uncleanness and sinful state.

To have God look on you and be well pleased, to have GOD label you as "very good" when Yeshua in Luke 18:19 reminds that only God is good, that's just unfathomable. 

This is a mighty love and Providence from God.

Strong's:

diligently, especially, exceedingly, far, fast, good, greatly, louder and louder,

From the same as 'uwd; properly, vehemence, i.e. (with or without preposition) vehemently; by implication, wholly, speedily, etc. (often with other words as an intensive or superlative; especially when repeated) -- diligently, especially, exceeding(-ly), far, fast, good, great(-ly), X louder and louder, might(-ily, -y), (so) much, quickly, (so) sore, utterly, very (+ much, sore), well.

MEAT: [ARCHAIC] FOOD OF ANY KIND

Blessed (from Strong's) [adoration]

[ADORATION definition: made holy; consecrated]

Consecrated definition: having been made or declared sacred.

This puts the fall in a much deeper solemn and somber tone. God not only created them, He bestowed them with the absolute honor of His own likeness, and He made them holy and consecrated. They were completely pure in the purest form of innocence when created by Hashem.

"Let US MAKE man"

Who MADE man? US

Who CREATED man? GOD

GOD is the same US (Trinity)

Again God speaks, and it is so. Here He uses "our" because He is speaking to Another who is on equal being as He. Jesus is here, as is the Holy SPIRIT who was hovering over the waters in verse 2.

In researching, there is some marine life that is capable of reproducing on it's own. Not so for birds, and every time it has been found that birds have reproduced without a male's fertilization, it has been a miniscule handful of times and ALWAYS in captivity. In this verse God separates marine life with "their" and birds with "his".

The accuracy and inerrancy of God.
