Ask AI: Write a hypothetical scenario where fantasy elves (not Christmas/Holiday elves, fantasy elves) were real human species.

Scenario: In a world as diverse as ours, imagine a parallel reality where humans are not the only evolved species cohabitating planet Earth. Alongside humans, a separate species known as Elves matured and flourished over many millennia. Although Elves are a part of many human myths, akin to mermaids and unicorns, this reality is far from mythical. These Elves are an anthropologically distinct species, deriving from the same evolutionary tree as humans but following a separate branch. Both human and Elf ancestors recognized and respected each other, existing in a sort of symbiosis. Over time, this has led to a world where humans and Elves coexist in societies as diverse as their individual cultures. Shimmering cities stretch up among redwoods, built in harmony with the natural environment. Here is where our Elven brethren live, in a region respected as Elven territory. The grandeur of their architected nature is awe-inspiring yet entirely sustainable. Their affinity for the forest is not just spiritual or aesthetical – it’s biological. Elves, after all, have a longer lifespan, benefiting from a different metabolism and a more robust immune response. The Elves, being more attuned to nature and having better low-light vision, are nocturnal and tend to be more active during twilight hours. They have contributed significantly to advances in astronomy, leading to a shared calendar system and sophisticated navigational techniques. While the Elven language is different - rhythmic and musical, many have learned human tongues and vice versa. J.R.R Tolkien's descriptions share eerie similarities with our real-life neighbors, minus the magical abilities. In this parallel world, relations between humans and Elves fluctuate and develop over time, much like international relations within the human world. There are alliances, tensions, cultural exchanges, and mutual cooperation in world matters. Both bring unique capabilities and perspectives on global challenges like Climate Change and Resource Conservation. Elven serene music, ethereal architecture, and sustainable technologies have forever influenced human culture and innovation. In turn, Elves have adapted and learnt from various human sciences and social constructs, blending the best of both worlds. Though there are many challenges presented through this interspecies cohabitation, this world benefits from a richer, more diverse array of cultures, technologies, languages, and arts. In this parallel universe, there exists a beautiful demonstration of unity in diversity, showcasing that despite distinct evolutionary paths, peaceful coexistence and mutual growth can indeed be attained.
