We tend to think that the concept of resurrection emerged in the New Testament, but that’s not true.  Long before the New Testament was penned, there were several texts that spoke of resurrection, including 2 Maccabees, 1 Enoch, Psalms of Solomon, and the Dead Sea Scrolls.  These, combined with archaeology and our Old and New Testament canon, provide internal evidence for the resurrection.  If you’re ready to look, the evidence is there. 2 Maccabees 7.
