I wrote this in a rush so here is my clarified point:

"Adama" means "Land", "Earth", or "Ground".

"Adam" means "Man" or "Mankind". Adam was created by God from the ground, and "Adam" is derived from "Adama".

"Ben Adam" means "Human Being", literally "Son of Adam" or "Son of Man".

So when you say "Human Being" in Hebrew, you are directly referencing the creation of Man by God in Genesis.
