60-90 years after Jesus lived, some unknown persons wrote the gospels. These authors did not know Jesus and their stories were not even on eye-witness accounts. These stories built a mythology. We're asked to believe that Father God sent his "son" down to the Earth to be born of a virgin to die for our sins. He performed miracles, died, rose from the dead, and will come again. ONE THING IS A FACT: THIS STORY WAS MADE UP BY UNKNOWN PEOPLE WHO WOULD HAVE NO WAY OF KNOWING ANY OF THIS. Mythologies go back to the beginning of time -- DON'T FALL FOR IT.
The gospels were written by men who walked alongside Jesus and were taught by him. There are many things incorrect in your statement but for now, I will focus on how inaccurate your timeline is.
