Mike Wehner sums it up:
Maybe we’re the only intelligent life in the universe after all
Yeah, what if?
We know that space is filled with galaxies, and those galaxies are packed with stars, and those stars are orbited by a seemingly endless number of planets. We think that at least a chunk of those worlds are a lot like Earth, but whether any of them are home to intelligent life is anyone’s guess.
Based on what I see of humanity, maybe there is no intelligent life in the universe at all.
