The Question of the Greek New Testament

[Aractus]

Yes there is. Daniel B. Wallace said in 2012 that there is a first century Mark fragment that had yet to be published while debating Bart Ehrman (who knew nothing about it). Although the fragment has not yet been published, it has been confirmed to exist and to date to before 90 AD:

• Although the first-century gospel fragment is small, the text will provide clues as to whether the Gospel of Mark changed over time, Evans said.His own research is focused on analyzing the mummy mask texts, to try to determine how long people held onto them before disposing or reusing them. This can yield valuable information about how biblical texts were copied over time."We have every reason to believe that the original writings and their earliest copies would have been in circulation for a hundred years in most cases — in some cases much longer, even 200 years," he said.This means that "a scribe making a copy of a script in the third century could actually have at his disposal (the) first-century originals, or first-century copies, as well as second-century copies."

Whether you like it or not, Biblical scholars now do have a fragmentary source confirmed to have come from the first century, and they are working to put back together what they have and publish it later this year. From the time taken to have this published and the description it's safe to say it will be a more substantial publication than P52.

My my, isn't it interesting how you're never aware of any evidence?
