**This document explores the possibility of life on exoplanets by examining habitable zones and biosignatures.** It defines exoplanets and habitable zones (HZ), focusing on the conditions that allow liquid water to exist. **The study analyzes Earth's spectrum and identifies potential biosignatures, such as oxygen and the red edge, which could indicate the presence of life.** It discusses potential false positives and the characteristics of Earth-like planet atmospheres. **Finally, the report assesses the Kepler 62 system, specifically Kepler 62e and 62f, as potential candidates for habitable ocean planets, providing modeled spectra for analysis.**
