How can the world be rid of all religion?

The ultimate solution to any problem is education.

According to the Bible, it will be one day. God will judge Babylon, the mother church and all of her harlots.

And a mighty angel took up a stone like a great millstone, and cast it into the sea, saying, Thus with violence shall that great city Babylon be thrown down, and shall be found no more at all.

But that does not mean God's true people will be destroyed.

Religion is mostly philosophy that humans need in order to make sense of their "random" lives - we humans really need to find meaning and purpose in life

Not everyone can be a great leader for a cause, or save lives, or do some "meaningful" profession - to them philosophy gives comfort

Communism, how Stalin Lenin Mao Pol-Pot and even Hitler wanted...religion free world.

Widespread genocide is probably the only way to completely eradicate religion, but luckily nobody is that crazy and heartless AND powerful enough to pull it off.

The human race would have to cease to exist; so, when we all die out, then the world will be free of religion.

Free mandatory college educations for all.

Impossible. That's a fact! That's why it's still here.
