Harold, if you've solved an equation correctly there are workings and a mathematical proof as to WHY the answer is correct (And hence, implicitly, why the other numbers are not correct).   The problem theists have is the WHY?  On what basis can one say that the Christian god (for example) is the right answer and the members of the Greek pantheon are not?

I suspect the answer may have the word "faith" in it and even our beloved government wouldn't let someone through matric maths on that basis.
