[Love]

It is widely accepted that love exists so that people stick together in larger groups than a single individual. Just like how you have a pride of lions, a flock of birds, a herd of cows....etc. being in larger groups increases the likelihood of survival.

That is factually inaccurate. It is not anywhere near close to being "widely accepted" in science. Please provide the link from which you sourced this information.

As for the simplistic view of what love is....why does it need to be any more complex than it is? Why do you have to complicate something for your own satisfaction? Just because you are unsatisfied by an explanation doesn't mean you make up your own....of course I know love is more complex than JUST a chemical reaction, but that puts it in a quick and simple yet correct way.

I am not gratuitously over-complicating the matter, I simply disagree with you that something as complex as love can be DEFINED, even in simple terms, as a chemical reaction. Biochemical reactions do appear to be factor in the experience of love, but there is nowhere near enough peer reviewed scientific evidence for this to be accepted as scientific consensus; most of the speculations are based on neuroimaging observations of neural correlations when a person is experiencing love.
