The universe as we know it is more than 13.8 billion years old. If you had to compress that history into a single 24-hour day, then each second would represent around 160,000 years. Our solar system doesn’t form until 4:00 pm, and complex human civilization only emerges in the final fractions of a second before midnight. Yeah, it's a lot!
Every empire that rose and fell, every war, invention, and human memory fits into this single second. Indeed, a significant amount of time and history had already passed long before humans arrived.
