I brought up the star of Bethlehem because I thought it might interest you in strict scientific terms. I say this because even if someone thinks the three wise men are a myth, something occurred in the heavens coinciding with the birth of Christ and His death.
Anyway, I hope you due a search on this as well.
I recall reading about a triple conjunction of the planets, probably Jupiter, Venus, and I don't recall the third, which coincided with the approximate time of Jesus' birth. Is this what you're hinting at? I don't doubt it, as the calculations have been reportedly done by reputable astronomers. (I don't doubt the existence of Jesus either, just in case you've absorbed some of the rants which appear regularly in these threads. I've been accused of everything, but I generally don't respond to such material.)
