Most geologists date the Earth at 4.54 billion years and the oldest fossils (of stromatolites) date from around 3.8 billion years, so based on that, the Earth was without life for around 740 million years. However, there may well have been earlier life - there aren't that many sites with rocks dating back that far.

How long had earth existed before any life appeared?
Earth is estimated to be around 4.5 billion years old. The earliest signs of life on Earth date back to approximately 3.5 billion years ago, suggesting there was around 1 billion years between Earth's formation and the emergence of life.

The life of the earth--Also kindly let me know how many more years will earth exist?
The Earth is 4.5 billion years old. Life has been around for 3.5 billion years. Complex life forms originated about 500 million years ago. There is no telling if/when life will cease to exist on Earth or if/when it will be destroyed in space.
How many years did earth exist before there was evidence of life on?
Earth is estimated to be around 4.6 billion years old, and evidence of the first life forms dates back to about 3.5 billion years ago, in the form of fossilized microorganisms. This means there were around 1.1 billion years of Earth's existence before evidence of life appeared.
When did life first begin?
There is evidence of life on Earth since around 3.7 billion years ago.
How many years ago did life first begin on earth?
Life is estimated to have first begun on Earth around 3.5 to 4 billion years ago. This early life was likely in the form of single-celled organisms in the Earth's oceans.
For what percentage of time has life existed on Earth?
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).
What percentage of time has life existed on earth ( round to the nearest whole number?
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.
When did the earliest life evolve?
The first life apeared on earth some time around 4.4 billion years ago.
When did life life originate on this earth?
Life is believed to have originated on Earth around 4 billion years ago, shortly after the planet's formation. The exact timing is still debated among scientists, but the earliest evidence of life dates back to around 3.5 billion years ago in the form of microbial fossils.
