15. WRITE A COMPOSITION OF APPROXIMATELY 120 WORDS ABOUT THE TOPIC PROPOSED AND FOCUS STRICTLY ON IT: Are we alone in the universe? Do you believe there is life in outer space? Discuss.

Solución: Sample composition: The question of whether we are alone in the universe has fascinated humankind for centuries. Given the immense size of the cosmos, with billions of galaxies and trillions of stars, it seems mathematically improbable that Earth is the only planet supporting life. First of all, astronomers have discovered thousands of exoplanets in habitable zones, where conditions might allow liquid water to exist. Even if intelligent civilisations are rare, microscopic or primitive life forms could easily thrive in extreme extraterrestrial environments, such as underground oceans on icy moons like Europa. On the other hand, the vast distances between solar systems make direct communication or physical contact almost impossible with our current technology. In conclusion, while we have not yet found definitive proof, the vastness of the universe makes the existence of extraterrestrial life highly likely.
