Quick Thought 5 - The Universe: Where did it come from, and should we care?

The origin of the universe seems to be a hot topic for any religion, becuase most religions assume that an Atheist or Agnostic's thinking about how the universe must be flawed due to their own logic. If everything had to have a beginning, had to come from something, then what did the something from before the universe come from?

I happen to be a rather unconventional Atheist, and I believe something rather different. IMO, the universe has always been there. I'm quite a fan of the "Big Bounce" theory, where the universe forever expands and contracts. A fair few people won't have any problem with that, though a lot more probably will. To those who wildly disagree, if you can have faith in a God just because you read a book about him, why can't I believe in the universe having been around forever because I reckon that's right?

More importantly though, I think that people care far too much about this. Really, something that happened billions of years ago shouldn't be on your mind that much. If at all. You've got a life, why not just get on with it rather than avidly debating the finer details of how you got it in the first place. If there is a God, I'm pretty sure he would want me to use the life He gave me to the fullest.
