Michael Anthony Posted over 1 year ago Would religion exist if the first humans had our scientific knowledge? Yes. And this is not a debate, this is a fact. Scientology, Mormonism, Jehovah's Witnesses, Seventh Day Advents - They all answer your question. Their beliefs are no more or less credible than ancient religions, and just as far removed from reality. The difference is these are modern belief systems created regardless of what science told them.
