The Decline of Religion

Marx and Engels rejected religion. It's true that, scientifically speaking, God doesn't exist.
However, we don't reject it as completely as they did.
If peaceful religions maintain nonviolence and nonwar, that's fine for now.
However, recent research suggests that religion is in decline worldwide. Researchers say this isn't due to individual adults abandoning religion, but rather a generational phenomenon.

One reason for the decline of religion is that it's losing its relevance due to modernization, technological innovation, and advances in medicine and welfare. It might be worth remembering that.
