For how long has there been life on Earth

For how long has there been life on Earth?

The Correct Answer and Explanation is :

Life on Earth has existed for at least 3.5 billion years. The earliest undisputed evidence of life dates from the Eoarchean Era, over 3.5 billion years ago, following the solidification of Earth’s crust after the earlier molten Hadean Eon.

Some studies suggest that life may have emerged even earlier. For instance, biogenic graphite found in 3.7 billion-year-old metasedimentary rocks from Western Greenland indicates the presence of life at that time. citeturn0search0 Additionally, remains of biotic material found in 4.1 billion-year-old rocks in Western Australia hint at life existing shortly after Earth’s oceans formed.

This evidence points to the emergence of life relatively soon after Earth’s formation approximately 4.54 billion years ago, suggesting that life began to flourish within a billion years of the planet’s creation.

The persistence of life over such an extensive period has led to remarkable evolutionary developments, transitioning from simple single-celled organisms to the vast diversity of life we observe today. This long history underscores life’s resilience and its capacity to adapt to Earth’s changing environments.
