I have common sense. I ask the big questions.
Up above I mentioned that one thing you see is the recycling of previous religions upon the implementation of a new one. Here's something interesting:
Egyptian God Osiris:
Virgin Born
3 wise men announced his birth
Died and resurrected
His body represented by wheat cakes eaten by followers
Greek God Dionysus
Virgin Born on Winter Solstice
Star appeared above when he was born
Half Human-Half God
Died and resurrected
Phrygian/Greek God Attis
Virgin Born on Winter Solstice
Died to save humanity
Crucified
His body represented by bread eaten by followers
Resurrected at Vernal Equinox
Iranian/Mesopotamian/Zoroastrian God Mithra
Virgin born on Winter Solstice
3 wise men announced his birth
Performed miracles such as walking on water, curing disease, and exorcising demons
Had 12 apostles
Had a last supper
Died to save humanity
Resurrected
Ascended to heaven
Will return to judge mankind
There are others that fit this as well but I'm just picking a couple of the predominant religions of the time that were suppressed by Christianity.
Regardless of your religious beliefs I would actually recommend reading up on other creation myths since they're very interesting and might actually open your eyes to ask more questions rather than just accepting a book as real and your religion as the one true religion. Native American, Egyptian, Greek, etc. You'll get frustrated at the similarities but it'll be good for your soul.
