Scenario: You can go back to the past and film one event. What do you choose?

You are aware it took millions of years for the earth to create itself right? Seeing 5 minutes of this would be like staring at a picture.

So? To see the earth as a fiery ball of molten rock, inhabitable by anything, would be amazing. For something like that, to turn into the verdant planet we live on now? It's amazing.
