If we compress geologic time into a single year, the time since Columbus arrived in the New World in 1492 would represent just a fraction of a second. In this analogy, the entire history of Earth, spanning approximately 4.5 billion years, is condensed into 365 days. Therefore, Columbus's arrival would be equivalent to about 0.0000001 of a day, underscoring how recent human history is in the context of Earth's geological timeline.
