We have exactly zero writings of Socrates today, do you believe he existed?
If you take the four Gospels, and consider them as the four different accounts they are, written at four different places, at different times, by different people, then toss in Paul’s letters, and the Acts of the Apostles (written by the author of Luke) you’ll have more documented authors writing about Jesus than you have writing about Socrates.
The common confusion comes from looking at the Bible as one book, rather than as an anthology of 66 different books, which it is.
So, four or five different authors writing about Jesus.
Three authors writing about Socrates.
And not one scrap of paper remains written personally by either Jesus or Socrates. All that exists is oral traditions of each, recorded by others and passed down through time for thousands of years.
Again . . . Jesus and Socrates . . . why is one easier to accept than the other?
Your answer may say more about you than it says about Socrates or Jesus.
