History Of Life On Earth

The timeline of early life on Earth is debated, with the earliest irrefutable evidence of life dating to about 2.7 to 3.5 billion years ago, while some scientists suggest life may have originated as early as 3.7 to 4.5 billion years ago. Scientists use fossil evidence and chemical signatures to date the origins of life, but the record is complicated by the way Earth's ancient rocks have been weathered and recycled over billions of years. | Space Advances

We still don’t know exactly how the first living organisms formed. But tiny fossils show that life existed on Earth 3.5 billion years ago 🌍🧬 Early Earth was becoming the perfect environment for chemical experimentation - a place where simple molecules could combine, react, and eventually evolve into the first living cells. ⚗️✨ The origin of life remains one of science’s greatest mysteries… but every clue brings us closer.
