There weren no claims that Jesus was God incarnate until the gospel of John, which seems to have been written at the end of the first century.
The earlier Synoptic gospels do not make the claim. They imply Jesus was a human based on the Jewish concepts of the Son of Man, or the Jewish concept of an adopted son of God.
The synoptic gospels were written earlier than John, and themselves seem to be based on even earlier but now lost written sources (Gospel of Q + sources L and M).
John does not seem to have been aware of, or did not use as source material, the Gospel of Mark or the Q source material.
All other things being equal, I am going to put more stock in the materiel written closer in time to the actual life and ministry of Jesus, aka the synoptics. Research prove that memories fade, and legend starts to creep in by three generations after the given events.
