Science has not yet found what created the big bang we only know that it did happen and when we look at the early universe theirs evidence to support this. The big bang some how created all of the elements we have today you'll have to do more advanced research to find the real reason.

I can assure you no scientist would ever say their is no life outside of this planet.

That's the thing with science, a lot of it is assumptions and belief. No solid facts, it's similar to religion in that aspect of things; understand where I'm coming from?
