How Can I Believe It?

How can I believe something like the resurrection really happened? After all, coming back from the dead doesn't make any scientific sense, it hasn't been observed since, and how can we even trust the writings of those that wrote about Jesus raising from the dead? It all happened so long ago, how do we know the story about Him didn't change over time? While there are many questions people ask about the resurrection of Jesus, the testimony of the eyewitnesses proves credible.
