Fake. Proven so for almost 700 years now. Over. And over. And over.

Ancient writings?
"Every single non-Christian source from ancient times recognizes, implicitly or explicitly, that he was a real person who really existed." LOL you gotta be kidding me. Not one, none, zero, were even remotely contemporaneous with your non-existent Jesus.
Your list mentioned Christians, not Christ. No mention of him. None dude. Cope.
Here is a list:
Timeline of Supposed Eyewitnesses to Jesus: Born year Zero and died in 33
Flavius Josephus: 37 - c. 100
Clement of Rome: born ? – c. 98 - 102
Ignatius: c. 35 - 107
Pliny the Younger: c. 62 - 113
Suetonius: c. 75 - 160?
Tacitus: c. 55 - after 117
Polycarp: c. 69 - 155
Justin Martyr: c.114 -167
Lucian: c. 125 - 180
Clement of Alexandria: c. 150 - 211/216
Tertullian: c. 155 - 230
Origen: c.185 - c. 254
Cyprian of Carthage: c. 208 - 258
Eusebius: c. 235 - 339
As you can see, NONE, not a single one of these supposed witnesses were in ANY position to give a contemporary eyewitness account of the time in which Jesus supposedly lived, because none of them were even born yet during the period in question. And even the very earliest of these writings are nearly one hundred years after Jesus’ alleged birth. If that weren’t enough already, the fact is none of the so-called “testimonies” are very impressive. Few are even talking about Christ in any context. For the most part, they are discussing Christians, not Christ at all. The two that do (or just appear to) even mention Christ, namely those of Tacitus and Suetonius, are just snippets that happen to mention common Christian beliefs of their day in passing while actually discussing some other subject altogether, not making any grand pronouncements on Jesus’ historicity.
But there were many first century writers, philosophers, historians, and other commentators who had good reason to notice Jesus, and despite apologists’ fervent denials, a wealth of their writings still exists today. But these perfectly respectable sources are never on Christian lists of historical witnesses. They include important figures like Epictetus, Pomponius Mela, Martial, Juvenal, Seneca the Younger, Gallio, Seneca the Elder, Pliny the Elder, Plutarch, Justus of Tiberias, Philo of Alexandria, Nicolaus of Damascus and more. And these are just the contemporaries;
