I have a lot of respect for your attitude on this subject.
But one thing that many people who have a problem with religion don't understand is something that every mathemetician accepts in arithemetic. In arithemetic, if we are speaking in base 10 and if all other standard assumptions are true, there is only ONE correct answer for the question 2 + 2 =?
There may have been a thousand false answers given throughout time to a specific arithemetic question but there is only ONE correct answer.
If Deity exists then there are many false answers to the question: How should man worship and serve Deity? If there are millions of false answers to that question that in no way negates the validity of the correct answer.
