Because the carnal mind is enmity against God:
Romans 8:7
"Cosmologist and theoretical physicist Lawrence M. Krauss believes that religion could be eradicated — or at least largely removed from society — in just one generation.Krauss, who made this claim while delivering a speech to the Victorian Skeptics Cafe in Australia in late August, spoke, among other subjects, about how children should be taught about faith in schools, claiming that religious systems shouldn’t be treated “as if they’re all sacred.”
“What we need to do is present comparative religion as a bunch of interesting historical anecdotes and show the silly reasons why they each did what they did,” he said. “Instead of shying away from it, we have to explicitly educate people to confront their own misconceptions.”
Addressing the future of religion, Krauss cited gay marriage and slavery in offering up a dire prediction: that religion could be largely eradicated within just one generation’s time.
“Change is always one generation away,” the scientist said. “So if we can plant the seeds of doubt in our children, religion will go away in a generation, or at least largely go away — and that’s what I think we have an obligation to do.”
Krauss made waves earlier this year when he said during a separate appearance that teaching creationism to kids is akin to child abuse." TheBlaze
