Are there planets more habitable than Earth? Here's what scientists say

Could there be a planet better suited for life than Earth? Although no world has yet been confirmed to be more habitable than our own, scientists have identified characteristics that could favor the development of life on other planets. For billions of years, Earth has maintained conditions that allowed life to emerge and evolve, from the earliest microorganisms to the enormous diversity of species that exists today. However, its history has also been marked by extreme climate changes and mass extinctions. The discovery of thousands of exoplanets has led scientists to wonder whether worlds with even more favorable conditions for life could exist. Some studies suggest that certain planets might offer more stable environments, a greater diversity of habitats, and longer periods of habitability than Earth. Researchers have even proposed characteristics that could help identify them, although there is still no confirmed evidence of life beyond Earth.
