Here's why:
* He was created in the Garden of Eden: Adam was created by God and placed in a perfect environment where all his needs were met. He didn't need to work for food, shelter, or sustenance.
* His role was to care for the Garden: God instructed Adam to "till and keep" the Garden of Eden (Genesis 2:15). This was more of a responsibility than an occupation.
* He was given dominion over all creatures: God gave Adam dominion over all living creatures (Genesis 1:28). This was a responsibility and privilege rather than a job.
So, while Adam had tasks and responsibilities, he did not have a traditional "occupation" like we understand it today.
