But a fairytale with brass knobs.
The trope of "three days dead" was a signifyer for a Sun God in ancient literature, later applied to any hero who descends to hell and returns, think Ulysses, three days dead, and Orpheus going to see Eurydice in Hades for example.
Since the sun metaphorically dies for three and a half days at the winter solstice and metaphorically comes back to life again by virtue of the points at which the sun rises and sets having stopped for this period of time, on Christmas day start moving north again on the east horizon (the rebirth of the Sun God)
To attribute this "three days dead" experience to Jesus was to award him the mantle of divine glory as a super-hero. This was a necessary move on the part of the Jesus cult to have this included in scripture because earlier "Christ" literature gave no personal name, just the title; The Christ.
But hey! the more ancient fables which are retold by JW org as if they were true, the more JWs there will be who will wake up, join us and leave the cult to stew in it own ignorant juice. How anyone can see a divine hand at work in last years story of Lot and his daughters, beats me.
