Yep, so how do know that happened in the original creation week?
what are you asking ?
“And God saw
every thing that he had made, and, behold, it was very good. And the
evening and the morning were the sixth day.”
Genesis 1:31
chapter two takes a closer look at creation that we just got an overview of chapter one should end like this
“
Thus the heavens and the earth were finished, and all the host of them.
And
on the seventh day God ended his work which he had made; and
he rested on the seventh day from all his work which he had made.
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.”
Genesis 2:1-3
Seven days is that what you were asking ?
chapter two then goes back into a closer examination of what was priorly described for instance in chapter one we see an overview
“And
God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
And
the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good. And the evening and the morning were the third day.”
Genesis 1:11-13
But then chapter two reverts back into that timeline for a closer look at mans creation
“These are
the generations of the heavens and of the earth when they were created,
in the day 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.
But there went up a mist from the earth, and watered the whole face of the ground. And
the Lord God formed man of the dust of the ground,
and breathed into his nostrils the breath of life;
and man became a living soul.”
Genesis 2:4-7 KJV
it seems confusing because we read it chronologically , chapter two is a closer look at what happened in chapter one
