It was a literal day with a week of seven days, the same weekly cycle we have today.
"And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. These are the generations (plural, a thousand years) of the heavens and of the earth when they were created, in the day (singular, the Day of the Lord) that the Lord God made the earth and the heavens, And every plant of the field before it was in the earth, and every herb of the field before it grew: for the Lord God had not caused it to rain upon the earth, and there was not a man to till the ground."
No one tilled the earth, nor did a single wild thing come out of the ground for the entire Day that the Lord made the heavens and earth, in this period of that creation. The Day of the Lord was the Sabbath Day. The creating was the 6 literal days of that Day of the Lord, singular. God planted the Garden of Eden after the Day of the Lord. God let generations of life live as God had planned life to be, way before God even planted the Garden of Eden.
No verse states the evening and morning was the Sabbath day. Nor is it implied in Exodus 20:11
"For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it."
The 7th day started that rest, but no verse states God started work again after 24 hours. The Sabbath was the Day of the Lord. The last Sabbath is also a Day of the Lord. God told Israel to Remember the Sabbath Day, not the 7th day. The 7th day was to be kept holy to remember the Sabbath Day.
It was not the same weekly style. That is not the format of Genesis 2 at all. Genesis 2 is not a repeat of Genesis 1. Nor is it a totally seperate creation event after the 7th Day. Genesis 2 gives us the passing of time after the week given in Genesis 1.
The day of rest is not even mentioned in chapter 1 despite the chapter break. Chapter 2 is a different thought that declared all creation over before the day of rest is even mentioned.
The Garden of Eden was not created, but planted, and marked off to place Adam in, separate from the sons of God already established on the earth. The creation of Adam and all the animals in this chapter was already accomplished in the first chapter.
"And the Lord God planted a garden eastward in Eden; and there he put the man whom he had formed."
Yes, two different Hebrew words meaning two different things. One planted, the other created. What was created was declared finished after the 6th day, before the 7th day even started. What was planted was an event after the "day of rest". The Garden was after this "day of rest". Adam and the animals were created on the 6th day prior to the Day of rest.
"And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so."
"And out of the ground the Lord God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof."
The same creation event with different applications. Even though Genesis 2 is not a repeat of Genesis 1, it does address the same creation event, but chapter 2 gives us the purpose specific to Adam. Adam did not name the animals on the 6th day. Adam named them after the day of rest, after he was placed in the Garden.
Adam was not in the Garden at all during the Day of the Lord. There is no verse that even hints at that point.
Adam was chosen out of all the sons of God to represent God on earth. Abraham was chosen out of all the Gentiles to represent God on the earth. The 12 disciples were chosen by Christ to represent God on earth. The 144k are from the 12 tribes of Israel to represent God on the earth. All the redeemed are to represent God on the earth. Sometimes God calls a specific human or group of humans for a specific purpose and time.
The 144k are not just some general generic figurative symbolism needed to be interpreted by guessing. They will have an important role, even though we are never given the details.
