Genesis 1:31 declares to us that at the end of the sixth day of creation, God inspected the entire project and declared it to be “very good.” The text goes on to state that the next day He entered a rest (a Sabbath) from His creating activity. It is difficult to not infer from the text that creation was finished. His last act of creating was the creation of the man (male and female, with the female somehow inside or within the man). Later, He was to bring the woman out of the man, but that was not creation. She had already been created, albeit in the man, on the sixth day. Her coming forth was a kind of “birth” rather than an additional act of creation. (Some Jewish traditions have it that the woman was brought forth on either the thirteenth or the fifteenth day. I prefer day fifteen.)
Genesis 3:17-18, in contrast, speaks of the coming into being of “cursed ground” and “thorns and thistles” due to the mischief of the man and the woman in the matter regarding the fruit of the tree of the knowledge of good and evil. So, what caused thorns and thistles to appear in the “very good” creation? For that matter, did God originally create the ground in a “cursed” condition? Was the cursed condition of the ground a “very good” thing? Were thorns and thistles components of the original “very good” creation?
