If I were the only human on Earth, I would wander through the deserted cities, marveling at the remnants of a once-thriving civilization. With no one to judge or watch, I'd sing my heart out in empty concert halls, dance in the middle of abandoned streets, and visit museums as my personal playground.
I'd explore the world's wonders, from climbing the Great Wall of China to lounging on the beaches of Bora Bora. Nature would reclaim its territory, and I'd witness the untamed beauty of Earth's landscapes. I'd adopt animals from empty shelters, forming a bond with the only living creatures left.
In solitude, I'd read every book in libraries, learn forgotten languages, and ponder the mysteries of the universe. The world would be my canvas, and I'd paint my thoughts and dreams across it. Being the last human, I'd cherish the memories of humanity and strive to leave a mark on the silent planet.
