This Tumblr website has launched a Birther movement regarding Jesus. It's actually a challenge.

Please provide ONE single person, along with their authentic writing, that can prove the simple living-human, historical existence of the claimed, christian New Testament jesus the christ of Nazareth, that meets both (A & B) of our 2 simple requirements listed below: A.) A contemporary 1st century person that lived between the years of 1-36 CE, who was a first-hand eye-witness, who actually saw, met, spoke to, and knew jesus personally. B.) Provide this person’s original and authentic: secular, non-christian, non-religious, unbiased, non-bible, non-gospel, and non-scripture writing, that is directly about jesus (with references/citations to prove that this person actually wrote the work in question), officially dated by science, between the years of 1-53 CE. Additional religious or christian writings that can’t be used: papyri, uncials, minuscules, lectionaries, didache, apocrypha, gnostic, catechism, and pseudepigrapha.

In case some folks are tempted to reach for some of the classic "proofs," the site offers this scorecard:   The site also offers links to many other sites that challenge the existence (not merely the divinity) of Jesus, including:
