Exactly. Things only seem years ago because we have divided time into years and months. But The Earth doesn't turn all the way around in 24 hours exactly every day. Some days it's faster and some days it's slower based on--get this-- the wind blowing across the surface and pushing the Earth on it's axis faster. The sun doesn't follow the same track across the sky every day, it doesn't rise and set at the same times. Yet we still call it a day. We're slowly inching toward the sun in our orbit around it. That means our orbit is getting faster and our year is getting shorter, yet we stick to 365 days making up a year, as we call our trek around the sun. And even madder, every four years, we add an extra day cause the Earth wobbles in its orbit and its rotation!
Though some scientists say that time is the only thing that keeps everything from happening all at once.
And Special Relativity pretty much dictates that even though somethings seem simultaneous, if looked at on a smaller scale, you'll see one did happen before the other.
