Holocaust: Real or Fake?

If I was talking to someone who believed that the Holocaust was fake or made- up, we would most likely get into an argument. How is someone supposed to make- up the Holocaust? First of all, who would even do that? Second of all, how do you explain everything that happened? Over six million Jews just suddenly disappeared. Where did they go, if not to concentration camps? Are all of the pictures fake, how do you fake those? The ginormous camps out in the middle of nowhere, what are those? The tattoos on the captives arms, the gallery of old belongings of the captives, the pain and misery that they still feel today. How do you fake that? Is there any real evidence that the Holocaust didn't happen? There is a lot of evidence that it did. Think about that.
