My son no longer believes in god? Please help?

Okay I am a mother of one very good son, however recently he has been rejecting God and Christ. I am very worried he will go to hell! And I know who's fault it is. He has been hanging out with a school friend who is the embodiment of the devil. This is what she said to him: "There is no proof god exists. We are animals of evolution and it has scientific evidence to support this claim. How can a virgin magically get married? Religion is folklore that has been used to explain how the world works, and since it's in human nature to need support, having a higher being was the preferable choice. We now have science to explain and we are rejecting the evidence simply because we are in denial. We want to believe god exists. However, true fact says other wise. There is not a single bit of evidence to support the god exists." Yes I have typed this word for word. Lies. It's all her foul mouth can spew. She is 12 just like my son and she has brainwashed him. Science is nothing but lies! Please help me get my son back.
