Yes it is.
About 4.5 billion years.
When calculated according to the 4.6 billion years since earth was formed humans have live in it 0.09 percent of the time.

it has been for 90%
The Earth has had sunlight ever since it was formed about 4.54 billion years ago
Ever since the earth formed, about 4 billion years ago.
The Earth formed approximately 4.5 billion years ago. To calculate the number of days since then, you can multiply 4.5 billion years by the average number of days in a year, which is about 365.25 (accounting for leap years). This results in roughly 1.64 trillion days that have passed since the Earth's formation.
The Earth never became round. It has always been round in shape since it was formed at the beginning of time.
Ever since the world formed, temperature variations and the spinning of the earth has caused winds.
It is impossible to determine the exact number of snowflakes that have ever fallen from the sky since snowfall varies greatly by location, season, and year. However, it is estimated that trillions of snowflakes fall each year around the world.
