You have only begun to scratch the surface of this subject.

As you may note, Christians are a bunch of Sun worshippers.
"The Sun of God, died on the (Southern) Cross and was resurrected three days later"

12 disciples of the Sun of God - 12 astrological signs

And our current day of the week are from Norse gods

Thor's day
Freya's day

Which are the same planet/gods as many other religions.

It is even interesting that even in Japanese its is Sun-day, Moon-day... (with the actual symbols for sun and moon)

Many point to their being seven religions, each with their holy day.
But this is a harder one to fill in, as so much has fallen away with the dominant christian (Gregorian) calendar used around the globe.
