what moves the world?

I was trying to get breakfast this morning in the dinning hall of my working place, and when I passed in front of the kitchen door, I saw this youngish woman working in front of a grill there.
The kitchen had no windows and was probably hot. And she was there seriously working grilling some food.....

And I thought "why does she work there?"....and an answer came to my head: "she might have a son and she wants the best for him and she works there for him......she was doing it because of love........"

Then I remember that I thought something similar the other day when I was going in a bus: "what makes this driver come day after day and do this mechanical repetitive job, day after day, year after year?.......and I remember that a similar idea came to my mind: "he might have a daughter or a couple of dauhgters....and he loves them....and so he kind of do this for some kind of love......but love nevertheless......"

And I was still waiting on the line to get breakfast and a weird idea, or rather a question, appeared in my mind: " is it possible that loves moves this world more than we imagined?"....

extraterrestrials and love

Today we were walking through a village and we heard a love song (see link below)....

If some extraterrestrials would be approaching Earth for the first time, they would be detecting radio waves coming out of our planet......to analyze what kind of planet and living creatures lived on it.....

They would find that very often radio waves referred to something called "love", with many confusing aspects about it.......and normally spoken about in a peculiar way that was called "singing"....

What conclusion would they reach about Earth?.....what is love?...is it only human or a much more widespread phenomenon?

E: Perhaps we could begin by asking the connection between "love" and feelings or sentience. It is commonly accepted that love is a very strong feeling or emotion. Maybe we could talk about that?
