Though other authors go to great lengths investigating the claims listed in this discussion, my mission was to provide a brief synopsis that would help the reader distinguish between fact and fiction. Once the reader gets to the actual sources they will wonder how such claims even originated. If any of the critics cared to look into the facts for themselves before contributing to the propaganda, they would have been able to dismiss such claims immediately.
Certain coincidences between Jesus and other figures can only be expected due to sheer probability. As a modern example, let's look at some of the coincidences between Kennedy and Lincoln as taken from here:
Lincoln was elected to congress in 1846. Kennedy was elected to congress 1946 (Whereas Kennedy had instant success in legislative and executive politics, Lincoln suffered many defeats).
Lincoln was elected president in 1860. Kennedy was elected president in 1960. (Considering presidential elections were held every four years, this only brings the odds to 1 in 20).
The names Lincoln and Kennedy both contain seven letters (Until we consider their first names which destroys this parallel).
Both were presidents during times of major changes in civil rights (So were their successors and several other presidents).
Both presidents were killed by an assassin's bullet on a Friday (This holds only a one is seven chance).
Both assassins were known by three names consisting of 15 letters (Each man was not always referred to by three names. This mainly surfaced after they gained notoriety following the assassinations).
Both assassins were killed before their trials (Booth was killed when captured. Oswald was killed days after his arrest).
Both men were succeeded by men with the surname of Johnson (Considering the popularity of the surname Johnson among white males, it would be no more of a coincidence by comparing two Muslim men who share the name Mohammed.)
These coincidences may seem startling at first but really aren't that impressive once dissected. But in 2000 years, will future civilizations look back on the "ancient Americans" and accuse Kennedy of being a figment of our imaginations? Will it seem we were so intrigued with Abraham Lincoln that we invented a character to mirror a great American hero? The intelligent mind who is willing to do the research and look for the truth behind such propaganda can easily find it.
