The video explores the Faint Young Sun Paradox, which questions how early Earth remained warm despite a dimmer sun. Evidence suggests ancient Earth was warm and habitable, contradicting expectations of a frozen planet. Scientists propose that Earth's early atmosphere contained insulating gases, possibly from rocky debris or solar activity, which created a greenhouse effect. These gases may have also contributed to the development of life. As the sun continues to brighten, Earth's climate will change, potentially leading to a hotter, uninhabitable future.
