I posit that if we put mankind into a state of suspended animation, erased his memory, and removed all traces of recorded human thinking over the ages, that given a few thousand years after his wake-up science and it's principles would have been rediscovered, reaffirmed. All the sound principles would be once again discovered and leveraged into powerful technologies along lines similar to those we see today. In other words, gravity, thermodynamics, astromony, magnetism, and physics of the universe would eventually be considered 'true', and verifible. Mankind would use these fact bases for a general redevelopment of mankind's civilization toward something very similar to what we see. All that would have been lost is the time it took to reaquire them.
But religion, though it may also have again taken root in the minds of men due to our genitic disposition toward superstition, would be COMPLETELY different than the religion that exists today. There would be no 'truth' in Jesus, or 'truth' in Mohammed, or 'truth' in any particular beliefs that are today considered by the 'faithful believers' to have been handed down to men by GOD. There would be some similarity in beliefs, but the absolute truths that religion demands as 'correct' today would be missing.
So, though I have stated this hypothesis in clumsy terms, in short, religion would be just what it is today - a crutch devised within the confines of mortal minds, primarily to assuage the fear of death, and used by the higher ranks to control the masses. Religion, faith, belief, are just constructs with motive, but no substance.
But science would again attain to the same 'truths' as in the past - for these are really the residence of truth.
Opinions?
