I'm glad you mentioned survivorship bias. It allows us to consider the possibility that there were reasons why the story of the resurrection of Christ would be more likely to survive than others.

The story of a great savior dying and/or descending into Hell to save someone they love was very old even at the time. The cult of Persephone was well-known to the Jews; Persephone spending a season each year in Hades bought life for the land and special rewards for followers in the afterlife. Gilgamesh went into the depths to save his dearest friend Enkidu; Gilgamesh is thought to have lived around 2500 BC, and the Epic of Gilgamesh was well-known to the ancient world (one copy was dated to the 7th century BC).

Those are stories Jesus and his contemporaries would already have heard. Plus, they have come through the ages to us today. The story of Jesus going to Hell and coming back followed a well-trodden path, one that made many a religion popular.
