The third group is like me PIMA. Agnosticism means you doubt either option will have proof presented. Both groups claim to have have proof but it can all be argued against that it’s not actually proof of their theory but actually proof of the opposing theory.
I think it is much harder to prove god exists than to prove he doesnt. What is the criteria that would prove god exists?
I think it was Ricky Gervais that said that if you took away all knowledge of both religion and science, science would eventually be re-discovered and be exactly the same. Religion would be totally different.
However, I would add to this that religion would probably be the same in the way it is now. That is, every religion teaches its members they have a chance to cheat death - provided they follow the rules of that particular religion.
Yes Meaninglessness would certainly overcome.
Many would argue that life is ultimately meaningless now. Birth, procreation, death- just like every other thing. Eventually we are all forgotten.
