I think I'm losing my faith?

I was raised a Catholic. I was baptized, I went to church, I had my First Communion, prayed, confessed, I did all these things only because my family did them. Now I question my religion. I just don't really understand why people look up to these imaginary beings. I learned about evolution, and science in school. That all makes sense to me. Charles Darwin's Theory of Evolution just makes more sense to me. In my opinion. I'm really confused at this point. I'm so used to believing in God and Jesus Christ, I can't just throw that away, but I lean more towards evolution. What should I do? Yes, this is a serious question. Please no sarcasm.
