The Universe is Incredibly Big, Both in Space and Time

If the entire history timeline of the universe was compressed to a single calendar year, modern humans would appear on December 31st at about 11:59pm.

Consider the Big Bang happened on January 1st midnight, then :

First atoms were formed an hour later at, 1 AM
Sun was born on September 1
Earth was born on September 11
Dinosaurs appeared on December 27 and became extinct on December 30

Yes, last day of the year and still humans didn`t appear on earth.

So, first humans/homo sapiens arise on December 31st, 11.39 PM
First man walks on Moon on December 31st, PM
And we close the calendar with Present day being next January 1st, midnight
