What percent of the earths history has man been in existence?

Humans have existed for approximately 200,000 to 300,000 years, which is a tiny fraction of Earth's 4.5 billion-year history. This means humans have been around for about 0.004% to 0.007% of the Earth's existence. In geological terms, this is a minuscule period, highlighting how recent human history is compared to the planet's overall timeline.
