Asteroid impacts billions of years ago may have been the hidden catalysts for life on Earth—cracking the planet’s crust to create vast, heated hydrothermal systems that could have nurtured the first living organisms. These collisions, once seen only as destructive, generated underground water networks far exceeding Yellowstone’s scale, providing the mineral-rich, warm environments ideal for prebiotic chemistry. The research reveals how asteroid size, speed, and Earth’s internal heat combined to make the crust permeable for hundreds of millions of years, turning cosmic threats into life’s…
