So let's move on, to the past. What does Newton's Flaming Laser Sword tell us about the past? I mean it doesn't exist in the same way as Gravity or Light or Protons do. We can't do experiments on it, build control groups, run trials. The past, just is, what it was.

We will one day be the past, and no matter how well we try to record our stories, ourselves, without time machines, future archaeologists are going to have to make a lot of guesses about us, but that's kind of cool.
Future humans will likely no way more than us today, about medicine, about exoplanets about physics.
But one thing they almost surely will not more about than then we do is today.
Will your great great great great grandkids know your name? Will aliens, who visit the Earth millions of years after humans leave, or go extinct, know that Animorphs, was just a fiction not a history of our people? You are destined to become whatever the future thinks you were if you're lucky.

Vandals, fire, natural disaster, conquerors, thieves, all of these forces obscure facts overtime, but no matter how well we tried to preserve today for future history books, there's one type of fog we are unlikely to avoid.
