So, Earth is still special by comparison? This stuff is so hard to wrap your brain around! I WANT us to be, ‘the only ones’ with carbon-based Life and a History going back eons.
But, I’m not averse to inter-stellar company. ;)
There may have been many forms of sentient life. Possibly on thousands of planets. But time is so huge, who knows how many might exist at the same time? Our sun is 4.6 billion years old, and we have existed for a blink of an eye in that time. And the sun is thought to be a third generation star. Thousands of civilizations could have risen and fell before our solar system even existed. Between the vastness of time and space, I doubt we will ever meet our neighbors.
