**Chapter 1: A World of Giants**
### Prologue
The year is 2023. The sun rises over the expansive city of Los Angeles, weaving its golden tendrils through a skyline dominated by sleek skyscrapers and almost anachronistic prehuman wonders. Traffic hums in a synchronized chaos that a city of millions inherently commands. Yet, interwoven with this modernity, unmissable diversions sit at every turn: Columbian mammoths lumbering by the downtown lake, Shasta ground sloths casually munching on foliage between two coffee shops, dire wolves trotting alongside joggers, and the unmistakable silhouette of a North American scimitar cat watching over urban sprawl from a hill.
The Late Pleistocene extinctions never happened, painting a world where natural history magnificently collided with human ingenuity, creating a complex tapestry of life and interaction.
### Scene 1: Morning Commute
In the heart of Silicon Valley, John Davis sips his morning latte made with Colombian beans, as mammoths graze on the metropolitan foliage of San Francisco’s urban parks, rooted firmly against skyscraping backdrops. He boards a self-driving electric bus, where a dire wolf lazily rests beneath the seating, accustomed to human presence, another fellow creature of the modern world.
"Crazy how normal this feels," John says, hoping for a response from the person seated beside him. It’s Samira, an ecological engineer specializing in megafauna habitats. She nods.
"Our ancestors shaped their myths around these creatures; we shaped our cities," she responds, adjusting her glasses that glint in the morning sun. "We've adapted, as have they."
### Scene 2: Urban Wonders
Meanwhile, in the heart of New York’s Central Park, a curious spectacle ensues. Schoolchildren gather around Mr. Randal, a park ranger, as he narrates stories of ancient spirits. Beside him stands a serene Columbian mammoth, instinctively flapping its large ears to ward off the mild autumn chill, marking a dynamic range of reverence and familiarity.
"This here is Luna, Central Park’s oldest resident," Mr. Randal shares, patting her leathery trunk. "In some cultures, she represents wisdom, longevity, and the thread connecting us to our ancient past."
The children marvel, some envisioning Luna’s ancestors wandering these same lands millennia ago, while others are reminded of cartoons and adventure stories where such creatures elegantly blend fantasy and reality.
### Scene 3: Nightwatchers
As night falls over the Australian Outback, an entirely different scene unfolds. The cacophonous sounds of wildlife take on a symphonic quality. Thylacines rustle in the underbrush, while deep, resonant calls of Marsupial lions drift on the cool desert air. This ancient chorus is punctuated by modern technology: drones, camera traps, and bioluminescent pathways installed by scientists ushering in a newfound era of harmonious coexistence.
"You see, it's always about balance," Professor Mira Chen addresses her team, watching over the night activity through a sophisticated network of cameras. "Understanding these giants in the scope of our modern world could guide future conservation efforts globally."
The sight is surreal: Giant short-faced kangaroos running under the starlit sky accompanied by the occasional hum of a droning quadcopter documenting their movements.
### Scene 4: Coexistence and Conflict
At dawn in the bustling streets of Rio de Janeiro, a different truth surfaces. Amid ecosystem equilibrium, humanity still grapples with the forces of nature. On the fringes of the city, giant vampire bats clash with urban light pollution, and Toxodon herds disrupt traffic, showcasing the constant negotiation between wild and urban life.
"And in today's news," a reporter's voice echoes through a public space, "several neighborhoods experience unusual disruptions due to large herds of Toxodon migrating through. Local authorities advise caution and have rerouted public transportation."
The recurrent theme of conflict and adaptation paints the background of Melina's daily ride to her engineering job. She scrolls through her social media feed, glancing at posts sharing tips on coexisting with Pleistocene megafauna—human ingenuity and age-old instincts finding a delicate equilibrium.
### Epilogue
As the sun sets across different horizons, it is clearer than ever that the survival of megafauna has not just altered landscapes; it has transformed human behavior, culture, and connectivity across the globe. The world is now a rich amalgamation of past and present, where coexistence goes beyond a rarity and becomes the new norm.
From the skies, Garuda-like silhouettes of condors, teratorns, and eagles glide over canyons, valleys, and urban jungles. On the ground, humans and megafauna uphold an enduring dialogue of coexistence—each a testament to an earth capable of evolution, balance, and a shared future of mutual adaptation.
What began as a mere possibility, is now an alternate reality—one where the Late Pleistocene inhabitants adapt and thrive in the hum of modernity, an indelible stitching in the fabric of our shared existence. And somewhere, amidst these primeval relationships and futuristic innovations, humanity discovers a richer, deeper connection to the earth—a living, breathing legacy of survival.

Prompt: Write a alternate history scenario, where the "Late Pleistocene extinctions" in North America, South America, or Australia never happened, thus allowing the many fauna and megafauna from these three continents to naturally survive into modern times (whilst also having our current animals still existing in modern times). This series would also showcase these animals' interaction with the modern world. The human civilization (cities, technologies, religions/myths, languages, cultures, food, etc) should be mostly the same as it is in our timeline, only this time with the otherwise-extinct fauna and megafauna still around in addition to fauna and megafauna we currently have in our timeline (which also exist in this timeline) in the wilderness, as well as in the human settlements (in some small adaptable species like some small-to-medium-sized ground sloth species and any vampire bat species, just to name a few), with the humans not viewing any of the otherwise-extinct animals as prehistoric animals (since humans are aware of their further survival and their existence in modern times like all other modern animals) and are considered as familiar modern animals.
