Humans have existed for only about 0.2% of Earth's history, which is approximately 200,000 years out of Earth's 4.5 billion-year history. This indicates that humans are a relatively recent addition to the planet.
The earth is around 4.5 billion years old. Human-like animals have been around for about 6 million years, but modern humans only showed up about 200,000 years ago. You can see, this is a very short part of the total lifespan of the planet.
No, it is not for only humans. It existed long before humans appeared and will exist long after we are gone; in that time, it has, is and will support hundreds of millions of other types of organism.
Hominids have existed for approximately 2-3% of the total time that life has been present on Earth, which is estimated to be around 3.5 billion years. This means that hominids have been around for roughly 6-7 million years.
Homo sapiens have existed on Earth for approximately 300,000 years.
The modern form of humans (i.e. homo sapiens sapiens) evolved about 200,000 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 %
Humans have been on Earth for approximately 0.2% of Earth's history, which is estimated to be around 4.5 billion years. This means humans have been around for about 200,000 years.
divide the smaller number by the bigger number to get a percentage: age of the earth is 4.54×10^9 give or take a year. that's basically: 4,540,000,000years assuming humans existed for 160,000years 160,000/4,540,000,000=3.52422907×10^-5 basically 0.00003 to turn that into a percentage you move the decimal point to the right two space: .003% THUS: human history accounts for only .003% of earth's entire history.
Life on Earth has existed for approximately 3.5 billion years. Given that the Earth is about 4.5 billion years old, life has been present for around 78% of Earth's history. Rounding to the nearest whole number, life has existed on Earth for about 78% of the time.
Since humans and sheep have co-existed on planet Earth for ages, even before humans began writing, that date has been lost to history.
Humans and animals that grow fleece have existed together on earth since long before humans taught themselves to write. The name you want has been lost to history.
The first person to discover rocks was not a specific individual, as rocks have existed on Earth long before humans. Geologists and scientists study rocks to learn about the Earth's history and processes.
Life has existed on Earth for approximately 3.5 billion years, which accounts for around 75% of the total time that the planet has existed (about 4.6 billion years).
it has been for 90%
Atoms existed long before humans. Atoms are the basic building blocks of matter and have been present in the universe for billions of years. Humans, on the other hand, evolved much later in Earth's history.
Economics or better said, economic policies have existed for as long as humans occupied the Earth. They are a part of human history. As being a part of history it has a relationship with history. Additionally, economic history" is a field within its own boundaries yet is part of hum overall history.
