Zeitgeist - Part 1 The biggest of all myths

Zeitgeist [(tseyt-geyst, zeyt-geyst)] The general moral, intellectual, and cultural climate of an era; Zeitgeist is German for “time-spirit.”

Inspired by the Zeitgeist documentary, which i encourage you to download and watch, i wanted to write a few things about the three major sections of the world that the documentary adresses.
Some of you, probably have researched and are aware of these matters. But let's take a look at the first part of our documentary: "The biggest of all myths : Religion"

Countless times, questions about the major subject that occupies our thoughts, have been brought up for discussion and research. Who made the world as we know it, how can a female human bring a child to life and still be sexually pure. Does any God at all exist, and who's God is that? Is he Buddha, Jesus, some ancient Greek God, some ancient Egyptian God? Why Jesus chose to be buried for 3 days and resurrected on the fourth day? What does the star that pointed out his place of birth, to the "3 magicians" mean? Who were those "3 magicians" or the "3 kings" that brought gifts for little Jesus ? Who is the "King of Kings" , the "Lamb of God" Why philosophers and historicals that lived at the same age of Jesus or near that never wrote anything about it, even thought it kinda changed the world?
Which are the similarities of ancient religions many years before the birth of Jesus and how did this affect Christianity? Why was the cross selected for the emblem of the biggest currently religion of the world? Why Jesus chose to have 12 followers/students ?

I'm pretty sure many of these questions have not been answered, despite of the numerous times you banged your head on the wall, trying to find the truth. Also a lot of people couldn't even create those questions in their minds.

Here is a little,some kind of spoiler, to persuade you see Zeitgeist The Documentary. Based on historical facts, the only God that exists is the sun. One God, One Nation
