the Hebrew word translated “replenish” means “to-fill”
I believe for God, he only needs 6 days, he stopped on the 7th day
“You don’t need billions of years. this argument is just to support evolutionary theory.”
Genesis 1:2:
“And the earth was “Hayah - became” without form, and void”
Of course, God would not initially create the earth without form and void:
Isaiah 45:18
“For thus says the LORD, Who created the heavens, Who is God, Who formed the earth and made it, Who has established it, Who did not create it in vain “Tohuw - empty, formless and chaos”, Who formed it to be inhabited: “I am the LORD, and there is no other.”
And yes, since God created man in Genesis after Genesis 1:2 there would be no evolutionary connection between man and any life that existed prior to Genesis 1:2.
