Is the story of Jesus based on pagan mythology?

Reason 24 of the book Twenty-Six Reasons Jews Don't Believe in Jesus claims that Jesus and the narratives about him were created by combining elements from the Bible with pagan mythology and mystery religions of the ancient world.

This teaching takes the time to explore a few of the alleged parallels between the story of Yeshua and stories from mythology, revealing a loaded agenda of junk scholarship which intentionally twists the truth.
