Rav Yosef Albo (Sefer Halkkarim 3:2) explains that the expression 'Ki Tov' is used to describe something that has reached i.e. fulfilled its potential and reached its (goal, purpose) shleimus (perfection). For this reason Rashi (Bereshit 1:7) writes that the Torah does not use the expression 'Ki Tov' in conjunction with the second day of Creation as the formation of the waters that began on that day was not completed until the third day of Creation. And because the Torah doesn׳t explicitly state that man's creation was Tov, it is said man must work at perfecting himself, at fulfilling his potential and purpose, until he develops to the level of Tov.
Secondly after Adam HaRishon was made and placed in a Gan b'Eden and had been given certain tasks the Torah teaches that HaShem saw that it was not good for man to be alone/lonely/on himself. So He would make him an Ezer Kenegdo.
- Did HaShem made Adam HaRishon having a lack, shortage or deficiency that he could not be or perform the Will of HaShem on his own?; and what kind of missing elements are we speaking of.
- And if he was in need of help, what was it he needed help with/for?
- And looking at 1 & 2 than why didn't HaShem made them both at the first place? (Why first make Adam, then bringing the Animals in order to show that those are not worthy of being an ezer kenegdo for Adam, and then make Chava?)
