This is why we know that there must be a God. This universe of ours could not have just come out of nowhere. Of course, the next question that many (stupid) people ask is: then who created God? If there must be a creator, then who created the creator? Well, I have an answer to that.
Science has discovered that the Big Bang was the beginning not just of space, but also of time. So, we know from both this and from The Bible that there was an "in the beginning..." Therefore, God must exist OUTSIDE of space and time in order to have created that which began both space and time.
It just makes sense, right? But it doesn't answer the question. What created the creator? Obviously, if there can be a plane of existence that exists outside of space and time, then there must be a plane of existence that exists outside of that plane of existence?
Impossible, you say? Here's a bit of logic thrown your way:
If you're in your house, you can step outside it, right? Well, how can you step outside the outside of your house? Well, how about leaving the atmosphere of the Earth? You'd certainly be OUTSIDE the OUTSIDE, wouldn't you?
This is why the creator's creator MUST exist outside the outside of space and time. And who is that creator? The Flying Spaghetti Monster. Ramen.
