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.

During the recent ice age, glaciers covered almost 30 percent of earths land.
The division of geologic time that makes up about 88 percent of Earth's history is called the Precambrian eon. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago.
53 percent of Earth's diameter is approximately 6,465 kilometers.

The Precambrian era makes up about 88 percent of Earth's history. It started with the formation of the Earth around 4.6 billion years ago and lasted until about 541 million years ago.
That depends on how long ago humans developed. Assume 100,000 years, the earth is about 4,000,000,000 years old. So% = 100,000 / 4,000,000,000 x 100 = 0.0025 %
