This might not sound intelligent, figuring that I am 16 years old and I do not have an extensive vocabulary as I would like. But, getting to the question, If we ever find out if there is really a God in some shape or form and that the evolutionary theory or "darwinism" is in fact not true, do you believe that it would be mass destruction and chaos in this world due to the fact that many people's beliefs have gone to waste?
If someone's belief about something turns out to be wrong, that doesn't show that his belief was "wasted". Perhaps it was his false belief that led others (or himself) later to arrive at a correct belief. True beliefs usually don't spring into being from nothing; they gradually emerge from a fertile soup of false beliefs. And this process is usually gradual enough that arriving at the truth doesn't have the dislocating consequences you mention.
