Because there is no downside
Sure, unless you care about LGBT+ people not being discriminated against and murdered. And unless you care about teaching strong critical thinking to avoid conspiracies including anti-vax. And unless you care about the future of the planet in the face of climate change which is largely ignored by religious people who are more focused on the next life than this one. And unless, and unless, and unless…
There are tons of downsides.
As the only way in which the human condition can be contextualised is in a world that is created, and religions are the keepers of that knowledge.
Yeah no, we can contextualize with rational thought, it’s just that more work needs to be done that has historically been stifled by religion considering they have historically killed people who didn’t go along with them. Religions don’t have some monopoly on knowledge in this field, what they have is some shit they just made up, some of which works, and a lot of which doesn’t. But they have no methodology by which to test which parts work and which don’t so they just push all of them regardless.
Dante’s Inferno went into detail that was not biblical, but there’s enough in the bible that writing it off completely is cherry picking.
“They will throw them into the blazing furnace, where there will be weeping and gnashing of teeth.”
"And these will go away into eternal punishment, but the righteous into eternal life.”
"But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.”
“And the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.”
