Are you seriously equating the validity of Washington's existence with Jesus?
Washington was written about every fricking day during his time.

So? All you have are written documents. All the "witnesses" are dead, no interviews to conduct. Any surviving written accounts aren't easy to access. The people that have access to them are experts, collectors of rare documents and museums, all of whom have a vested interest in keep the "historical Washington" alive and well.
Nobody wrote about Jesus for a century.
No. Mark may have been composed in the early 60s, but 70 CE at the latest. Jesus probably died in 30 or 33. The pertinent question, however, is
why he wasn't written about earlier.
