""""To think of everything that could be out there that we don't know anything about is mind-numbing."""""
That is exactly right. Our Sun is one star. There are billions of stars in our galaxy. And there are billions of galaxies in the universe. The numbers are just too large for the human brain to comprehend. So are the odds....
There are 100 billion neurons in the human brain.
There are 100 billion stars in the Milky Way.
There are 100 billion galaxies in the Hubble volume.
There are 100 billion Hubble volumes in the entire universe.
Maybe not exactly, but the orders of magnitude are close.
