Hi atheist !
Lets stop debating on God.
Now the question is:
Does love exist ? what do you say ?
I think human emotions exist. The human brain is a complex organ and there's a certain psychological and emotional component to our being. For this reason, it's quite common for humans to form bonds and connections to each other which would fall into the definition of what most people would understand as "love." It's not necessarily permanent or immutable - and can often fluctuate in intensity and sometimes mutate into something else (even jealousy and hatred).
Sometimes, it's more generalized, like when people say things like "I love America." I guess there can be different contexts and meanings whenever the word "love" is used.
Maybe it gets overused. A lot of media, too. All those books, stories, songs, movies - all about love. It's so popular and everywhere. Everyone loves love - or at least they love stories about love. It's in the media, plastered all over the place - especially around Christmastime. Love is a central message in many religions. For thousands of years, people have heard the notion that "ye shall love one another."
So, you'd think that, with all this talk about "love," there would be more of it in the world. Perhaps it's analogous to an unstable element which can sometimes be good and wonderful - but sometimes misused. Perhaps there's a certain power behind it which can either be used for good or bad.
