| How would the Kryptonians view this alien from Earth? |
"The universe is a pretty big place. If it's just us, seems like an awful waste of space." by Carl Sagan.
If there was only us in the whole history of the universe, the probability would be less than one in 10 billion trillion. That is less than 1/1000000000000000000000000. Billions of trillions of stars exist only for us to follow the Kardashians? Seems like a pretty weird plan from the Big (wo)man upstairs. Or there's no such plan at all? And civilizations are all around us, in both space and time? Blooming and fading like wildflowers?

Using this method, Frank and Sullivan calculated how unlikely life would be if there has never been another example of intelligent life among the universe’s twenty billion trillion stars, or even among just our own Milky Way galaxy’s hundred billion.
The results? Less than one in ten billion trillion. "To me, this implies that other intelligent, technology producing species very likely have evolved before us," said Frank. And when the equation is scaled down to include just our galaxy, the numbers are not as extreme.
However, the universe is more than 13 billion years old. "That means that even if there have been a thousand civilizations in our own galaxy, if they live only as long as we have been around -- roughly ten thousand years — then all of them are likely already extinct," explained Sullivan. "And others won't evolve until we are long gone."
