Human civilization has existed for approximately 10,000 years, which is a tiny fraction of Earth's history, estimated at about 4.5 billion years. This means that human civilization has been present for roughly 0.0002% of Earth's total history. In the context of the entire timeline of life on Earth, which spans around 3.5 billion years, human civilization still accounts for only about 0.0003% of that time.
