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.
