How old was earth when life appeared on it?
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
How long did earth exist before the first life forms?
The Earth formed about 4.6 billion years ago, and the first life forms are believed to have appeared around 3.5 to 4 billion years ago. This means there was a period of roughly 500 million to 1 billion years between the formation of Earth and the emergence of life.
When did life first appear in the Earth's ocean?
Life is believed to have first appeared in Earth's oceans around 3.5 billion years ago. This was in the form of single-celled organisms like bacteria and archaea. These early life forms were the foundation for all subsequent life on Earth.
What life on Earth came first?
Microscopic single-celled organisms such as bacteria and archaea were likely the first forms of life on Earth, appearing around 3.5 billion years ago. These simple organisms eventually evolved into more complex life forms over millions of years.

eff the time in wich life first evolved on earth!!
When did life first begin?

Where did life begin?
Life first began in the Earth's oceans, a few billion years ago. and cave men came from monkeys.
How many years ago did life on earth begin?
4.567 million years ago
When did life on earth begin to evolve?
Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.

When was first species on earth?
Scientific AnswerThe first bacterial life to appear on Earth was 3.46 billion years ago in the Precambian supereon. The first complex life appeared around 600 million years ago just preceding the Cambrian Explosion of life 530 million years ago.

When did the first life forms appear on Earth?
Scientists think that the first life forms appeared on Earth about 3.6 billion years ago. These were simple cells that eventually evolved into the abundance of life we see today.
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.

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.
What era was when life first flourished on Earth?
Life first flourished on Earth during the Precambrian era, which began around 4.6 billion years ago and lasted until approximately 541 million years ago. This era saw the emergence of diverse forms of single-celled organisms, marking the beginning of life's evolution on our planet.
