How old are living things?
Simple life forms like bacteria have on the Earth for about 3,500,000,000 years ago (3.5 billion years). Evidence of this was found in very old rocks in Australia. The estimated age of the earth is 4.5 billion years so life originated just 1 billion years after the earth formed.

Life has existed on earth for how long?
Life on Earth is estimated to have started around 3.5 to 3.8 billion years ago, with the first microorganisms appearing in the ancient oceans. This marks the beginning of the evolutionary journey that has led to the diverse array of life forms present on Earth today.
