What I want to know about my topic

The thing is that i wnat to know everything i can. Because I belive that if you find the true meaning of the word love yoiu find the true meaning of life. Since there is no one on earth that knows the true mening of life i don't think anyone will find the true meaning of love. I do have some questions.


* Where does love come from?

* How can some people just not love?

* Who first Loved?

* How do we love ?

* Do we need Love?
