I was recently in Greece and I visited the Acropiles a lion gate nearly a thousand years older than the Acropolis, the earliest known analog computer, plenty a beautiful cats and I even took a selfie in Delhi! Seeing all of these things and how old they were, made me wonder, how will we be remembered? How will future archaeologists react to the ruins of today's society that they find thousands of years from now? Will anything about you, in particular, be remembered?
And for that matter, how do we know that the past happened?

Not just the way we think it happened, but it all. Seriously, can you prove that the universe wasn't created last Thursday? That everything, every person, every memory you have and every photo you've taken, didn't pop into existence, Last week. Or five minutes ago?
