What is the point of love? Why do people fall in love? How?

There's a lot of science behind it honestly and sometimes I feel like love isn't even real.Well,real between humans.I can love an animal or object or show while with humans,I see baerly any point in dating and such.Love basiclly exsits to keep humans on the planet.But tbh there's stupidity(teens getting pregnant with consent and knowing they could get pregnant),and victums,so love is more like a nicer way of keeping humans on Earth,I geuss(?)
(Sorry if this sounds rude or stupid,it's See More just my opinion)

The point of love is to keep the human race going. People love people for many reasons. People want to feel loved so that they feel like they have a purpose. But you can't love anyone else without you knowing how to love yourself.

the point of love is.... i dunno and i don't freakin care >:)
