Need help introducing friends to Minecraft for the first time

I want to introduce some of my friends to Minecraft. They have never heard of it before and I am having trouble explaining them from the beginning since the scope of the game is very vast.

I want to give them a preview of the game before they start playing themselves, so I would prefer a video explaining the same. I tried to search for it on YouTube but I could personally find no video that could explain the premise and potential of the game from scratch. I tried to explain them via playing the game on my device too but that was of no meaningful help either since I have no personal worlds or builds to show.

Could someone please help me recommend some useful resource for this matter? I am sure they will come to love it once they get to properly understand it.
