Why do we humans exist? Without us the world would not have climate change, there would be more animals, some extinct

Question: Why do we humans exist? Without us the world would not have climate change, there would be more animals, some extinct animals would still be alive, there would be no deforestation and the world would be a much cleaner place to live in. Do humans have a special purpouse in life?

  You’re so right. No, I don’t think so. I think we are just a lucky combination of the dinosaurs going extinct so mammals could rise up and random mutations meaning we got bigger and bigger brains and cleverer and cleverer until we became top of the food chain. I think its just coincidental we came out on top. I think its up to the next generation of us to try and use our big brains for good though!
