In general, “Very good” is relative, i.e. better than “good” but not as good as “very, very good.” Certainly not absolute, i.e. “perfect.” Even if “very good” did mean “perfect” that could mean that creation including Adam was "fit for purpose".

What specifically does "very good" mean in Genesis 1:31:

> And God saw everything that he had made, and behold, it was **very good**. And there was evening and there was morning, the sixth day. <sub>[ESV](https://www.biblegateway.com/passage/?search=Gen+1%3A31&version=ESV)</sub>
