I personally am one of those strange people that believe in both God and science.
No, you do not. You could not "believe in science" when you say things like "I don't believe we evolved from monkeys". If you believed in science in any way, you would at least understand what evolution evidences. Humans are primates. Definitively. We merely share a distant, extinct, common ancestor with the other ape species that are still surviving today. Remember, 99.99% of all species that have ever lived on this planet are gone. Extinct. Never to be seen again. That is not creation (complete magical failure where most species die?), that is evolution. "although our DNA is very similar" also clearly evidences evolution.
Why we are here?
Not sure. I only know I'm tickled that I am...

















I don't see why people think there needs to be an all encompassing reason for us to be here. People make their own purpose in life based on what they perceive needs to be accomplished. e.g. a kid is fascinated in the anatomy of the human body so thinks that his purpose is to become a doctor and help people.
As for how, the other comments here explain it pretty well. the relation to a common ancestor understood through transitional fossils which is supported by DNA and taxonomical analysis. it is interesting and i would suggest picking up a few books on it at least.
I'm agnostic. I believe we evolved, likely by chance, and it doesn't matter why we are on this planet-- just that we are and we should make the best of it.
"why" to our existence unless someone gives it purpose. Give yourself purpose.
I hope you have a wonderful evening as well.
