philosophy

Last class we talked about god and the big bang theory. Our teacher asked questions about god that freaked me out. Not in a way that she was bashing my religion or anything but in a way that just had me asking questions. We always say that god has no beginning so he can't end. How does something not have a beginning? If he wasn't created how did he come to be? He was always here? It's weird to think that he was always there. For how long? Was there anything before God supposedly created everything? And when we started talking about the big bang theory I also started asking questions again to myself. So before the big bang theory there was nothing? I can't comprehend the notion that there was nothing. How can there be nothing? If there was indeed nothing, did time exist? It blows my mind. And then I started to think about dying. What if there is no heaven after death? What if it's just nothing? Is it just blackness? Would it be like sleeping? You'd just be dreaming forever? Or would it be like when your sleeping but you don't dream? But when you sleep and don't dream there's nothing in between. You go to sleep and then you wake up. If you die and it's like going to sleep without dreaming, what would you wake up to? Would you even wake up? Would you just be stuck in that weird spot between sleeping and not dreaming and waking up? This class is definitely blowing my mind so far but it's also opening me up to questions that I hadn't thought about before.
