A demigod being raised from the dead in order to redeem humanity was a common theme in Greek mythology and other ancient pagan religions that predate both Christianity and the Bible. One example is Attis, the Phrygian-Greek god of vegetation, which is dated to 1250 BCE. If we were to replace the name Jesus with Attis, then we would have strikingly familiar savior stories. In the mythological stories of Attis, he was divinely born of a virgin; he was hung on a tree and died; he descended into the underworld after his death; he was resurrected from the dead after three days; and he brought salvation with him in his rebirth. There are several other similarities between the stories about Attis and Jesus in this article, "Attis: Born of a Virgin on December 25th, Crucified and Resurrected after Three Days." And, like the myths about Attis, these other stories about Christ-like figures from Greek mythology and other ancient pagan religions predate Christianity and the Bible. I recommend learning more about Jesus in comparative mythology. You can start here: Jesus in comparative mythology. I recommend reading the following articles for more information as well. Of course, you can believe whatever you want.
