I believe in a combination of the two. Science gives answers to a lot of questions, but everything had to have started somewhere. It's not like the Big Bang just decided to happen, it had to have started somewhere. It just makes sense that there is something bigger than us that is in control. I mean science gives no definition as to why people have life. It gives the idea of evolution which I totally agree with and how everything was started with single celled organisms and all that stuff, but it only makes sense that something made everything happen as it did.
This is just my opinion as I am a Christian. Christians FTW
