If I could go back in time!

If I could go back in time I would go to the time when the pyramids were being built. I would take a camera so I can get good pictures of the tools that were used and how the Egyptians built the pyramids. No one knows how exactly they were built so I thought it would cool to see how they were built. But as I am looking at the pyramids I would want to stay hidden because they might think I was some kind of enemy. And that would be no fun to get caught then have to run away and hide. So then eventually I could go back to my own time.
