What if Earth had a twin planet in its orbit?

Imagine waking up to a sky where not one, but two celestial bodies dominate the horizon. Earth's long-lost twin, a mirror image of our blue planet, hangs in the heavens alongside our familiar moon. This isn't science fiction; it's a tantalizing "what if" scenario that could reshape everything we know about our world. How would this cosmic doppelganger affect Earth's tides, climate, and even the course of human history? Would we have raced to explore our twin before venturing into the depths of space? The implications are as vast as the cosmos itself, promising to challenge our understanding of geology, biology, and our very place in the universe. Buckle up as we embark on a mind-bending journey to explore the profound consequences of Earth's celestial sibling.
