The History of first life on our planet,
The earliest life on Earth is thought to have arisen around 3.5 to 4 billion years ago. The exact timeframe is difficult to pinpoint exactly due to the scarcity of geological and fossil data from that far period. The fossilized remnants of microbes such as bacteria and archaea provide the oldest evidence of life.

These early life forms were single-celled creatures that most likely lived in hydrothermal vents or shallow, warm oceans. The early Earth's atmosphere was significantly different from today's, with high amounts of gases such as methane, ammonia, and water vapor. Life is supposed to have originated when these basic creatures discovered the capacity to gather energy from their surroundings and reproduce.
