Yet here we are 2,000 years later. We have the internet. We're more literate. And yet people still believe those myths and superstitions from 2,000 years ago. And new ones like scientology are growing.
Actually, the non-religious worldwide are growing, in large measure due to the growing availability of information on the internet. It will take some time for religion to retreat to a small minority. After all we didn't get to this stage over night, but over the course of thousands of years. I highly doubt scientology is growing in developed countries where there is ready access to information about the religion through the internet.
