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

The observable universe, at approximately 13.8 billion years old, is in its early stages of star-forming potential, which may last for up to 100 trillion years. This suggests humanity may be among the first intelligent civilizations in a young, awakening cosmos, rather than latecomers to an ancient one. This perspective challenges the assumption that we are at the end of cosmic history and suggests that trillions of future civilizations, planets, and cultures could exist as new stellar systems f
