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.

How much of the earths water is ready for use by humans?
Less than 1 percent of Earth's water is ready for use by humans. Earth is approximately 71 percent water but of all this water only about 2.5 percent is fresh water with the rest being salt water and thus not fit for human consumption.

How does the existence of humans on earth compare with the duration of geological time?
Here's an example to demonstrate the length of time that human beings have existed when compared to the time from Earth's formation:Observe the length of your arm from your shoulder to your fingertips.

You have just erased the period of time in which Homo sapiens has existed.
