In this respect also, the history of Jesus Christ corresponds with that of other Sun-gods and Saviors, for they are nearly all represented as being born in a cave or dungeon. This is the dark abode from which the wandering Sun starts in the morning (Cox, Aryan Mythology, vol.i. p. 153). "As the Dawn springs fully armed from the forehead of the cloven Sky, so the eye first discerns the blue of heaven, as the first faint arch of light is seen in the East. This arch is the cave in which the infant is nourished until he reaches his full strength; in other words, until the day is fully come."
As the hour of his birth drew near, the mother became more beautiful, her form more brilliant, while the dungeon was filled with a heavenly light as when Zeus came to Danae in a golden shower (Cox, Aryan Mythology, vol. ii. p. 133).
At length the child is born, and a holt of serene light encircles his cradle, just as the Sun appears at early dawn in the East, in all its splendor. His presence reveals itself there, in the dark cave, by his first rays, which brightens the countenances of his mother and others who are present at his birth.
It is recorded in the Protevangelion, Apoc. ch. 14, that when Christ Jesus was born, all of a sudden there was a great light in the cave, so that their eyes could not bear it.
Answer for yourself: Coincidence? You will have to decide.
