I don't believe you...I don't believe there's an ounce of evidence...Prove it...
He said, the evidence suggests.
So you ask for the evidence that suggests the possibility?
That might be hard to digest. Which of course leaves it susceptible to those with agendas. Just look at the modern "scholarly" analysis of those in present day academia concerning the validity of the Gospel. They'll try to explain it all away, not believing (or not wanting to go on the record amongst their secular peers as to believing) the texts are accurate at all, when it comes to the various miracles.
They cannot quite go so far as to say that the entire story was made up (although many appear to wish to!) for there is too much other other-than-biblical record of many persons, and events, including mentions of the Christ Himself, the circumstance of His death, the disputations of the Jewish religious authorities that the body was stolen away, etc.
Here are just a few scholarly works about the origins of the Gospel of Matthew in Syriac.
