Why did Allah create Adam from clay and not with the word "Be"?

Adam, peace be upon him, was created from dust, then water was added to it, making it clay. Then it became "black putrid mud" (changed black clay), then it dried without fire, becoming "potter's clay." Then Allah breathed into it of His spirit, and it became a human. From this, several wisdoms can be deduced:

1. Demonstrating Allah's tremendous power: Allah created man from dust and clay to demonstrate His tremendous power. 2. Difference in the origin of creation according to the state of the created being: The difference in the origin of creation for angels (from light), devils (from fire), and humans (from dust and clay) is proportionate to the nature and characteristics of each. 3. Distinguishing Adam by singling him out for creation with Allah's own hands: This was an honor for him and a distinction from other creatures.
