When did people stop believing in the old gods like Greek and Norse? Did the Vikings just wake up one morning and think ”this is bullshit”?

Answer 1

European perspective.

1. The spread of Catholicism / Christianity, starting with Roman Emperor Constantine. Christians were pretty aggressive at spreading the faith, at least once they got to the point where they had material political and military power,
2. Arguably, the ‘old gods’ where a god would be dedicated to a specific purpose, desire or topic (god of fertility, hunting, farming, lost causes,…) was replaced with the Roman Catholic canonization of saints.
