Who Was the First Person to Use the Word “Salam”?

I wonder who used the word "salam" for the first time?

Answer:

Hz. Adam was the first person to use the word ‘salaam’

Narrated Abu Huraira:
The Prophet said, "Allah created Adam in his complete shape and form (directly), sixty cubits (about 30 meters) in height. When He created him, He said (to him), “Go and greet that group of sitting angels there, and listen what they will say in reply to you, for that will be your greeting and the greeting of your offspring."
Upon this Adam (went and) said:
'As-Salamu alaikum (Peace be upon you).' They replied, 'AsSalamu-'Alaika wa Rahmatullah (Peace and Allah's Mercy be on you) So they increased 'Wa Rahmatullah' The Prophet added 'So whoever will enter Paradise, will be of the shape and form of Adam. Since then the creation of Adam's (offspring) (i.e. stature of human beings is being diminished continuously) to the present time."
