A Bishop in the 17th century named Ussher figured the world must only be 6,000 years old, many Christians think this is stated in the bible, so anything that shows the Earth or universe is older then that they argue that it's wrong. If they knew their bible like they pretend to they'd know that the Big Bang doesn't conflict with their bible.
So in other words, in your book, the big bang is the only possibility, no room for discussion, YOUR belief that the big bang is what happened, is THE only possible way the earth was made. There would be no arguments again, ever, if everyone believed the world, according to mmcdoniugh, is exactly the way the earth was created. So everyone should agree with your idea, theory of the big bang, and all will be right with your big banged world. Do I understand your question right? Hahaha, just stay in school and don't do drugs!
