Searching for Life in the Galaxy: How life on Earth began

The video explores Earth's unique conditions that support life, tracing its origins from cosmic events like supernovae to the formation of the solar system and Earth. It discusses the development of Earth's atmosphere and the emergence of early life forms, such as prokaryotes, which eventually led to photosynthesis and an oxygen-rich atmosphere. The video highlights key evolutionary milestones, including the rise of multicellular organisms, sexual reproduction, and the diversification of species, culminating in the dominance of dinosaurs and the emergence of birds and flowering plants.
