Only if you were currently infected with smallpox.
Me too. The irony is that by going there, you most likely destroy it by accidentally spreading disease.
I would like to watch:
A caveman discover fire.
Smallpox doesn't exist outside of Atlanta and Russia anymore.
I would love to be present or witness the following:
1: Mankind making first contact with another sentient species from beyond our solar system (imagine the profound universal implications of that?)
2: Mankind's first mission outside of our solar system using "warp drive" or equivalent.
I doubt I'll be alive to see either though. So if I had a time machine. I'd go ahead, most certainly.
The talk between the pope and Atilla the Hun (what did the pope say??)
Thank you, this allowed me to get my smallpox booster before it was too late.
Battle of Iwo Jima (American side)
When someone woke up and noticed Jesus's body was gone. (I never exactly got the details of this, how did the part go again?)
I would have liked to see the Trinity test.
But to witness the Trinity test... well, I'd still never fully comprehend what it meant, but it was certainly a life- and world-changing moment.
