Why people believe in evolution of species? ?

Well,i'm not some kind of stupid creationist. And me also don't put a trust in biblical creationism which is of course ridiculous. It's just that so many contradictions between evolution and modern science...also no one can confirm evolution claims. It contradicts the Second Law of Thermodynamics, basic understanding of genetics etc. Besides,where's the Missing Links? So many questions can't be answered with proofs by evolution advocates.
