For example: One person believes Muhammad has brought truth to mankind and a revelation of the one true God, and that person has found peace through those teachings, and another follows the teachings of Buddha and believes he has found peace through walking in the right path. But since Buddha's path does not necessarily need God in it, there is a major conflict with Islam which requires rigid devotion to a Supreme God. These conflicts and disagreements are diametrically opposed to each other. It certainly seems they cannot both be correct. Who is right?
Can they both be right? Not to mention all the other religions, can they all be right?
