Stillabatross, a couple of comments:
1. Yes there are probably thousands of religions in existence in the world but it does not logically follow that they all must therefore be wrong. If that were the case then logically humanism would also be refuted as this is just as religious as any other philosophy.
2. The simple fact that there are so many religions is in fact consistent with what the bible actually teaches. God made us in His image so we are all naturally drawn to the questions of purpose, answered in many different ways by many different religions. It is sin that prevents us from seeing the truth. Even Richard Dawkins displays 'awe' and 'wonder' at 'nature'.
What we really need to do is honestly look at the actual evidence for any truth claim. This is where Jesus stands head and shoulders above the rest, a real man in real history that made claims that changed the world. Of course you could alternatively believe that matter and energy just popped into existence despite the laws of physics or life just started despite the laws of chemistry, but I would suspect that that path has more to do with rejecting accountability to God than any form of 'reason'.
