Why humans are so distinct from other species?

Imo it all has to do with evolution. Physically we're weaker than a lot of animals, slower, can't fly, can't kill prey with only our teeth/nails. Because of this we had to rely on our brain more than other animals, we had to come up with ways to kill larger animals, ways to keep ourselves warm, etc. Because we have to rely on our brain so much I believe our brain began to become more developed so that we can survive. The smarter ones of our species are the ones who survived and they passed down their genes and so on.
