You don’t believe? Not possible.

We live on a blue planet
that circles around a ball of fire
next to a moon that moves the sea,
and you don’t believe in miracles?

These are mind blowing large numbers

…Just how many planets are there?…There could be about 23 billion stars in our Milky Way galaxy, each harbouring Earth-sized planets with life-friendly temperatures on their surfaces. Twenty-three billion, give or take a few…Some studies produce numbers of Earth-sized planets closer to 17 billion…Others suggest a figure as low as 6 billion or so, but these are just the planets close to Earth in size. If we extend our reach to slightly larger worlds, the places now known as ‘super-Earths’, we’re back into the tens of billions. No matter how you slice the cosmic cake, you end up with a vast wedge of planets that we’d be happy to go and study, perhaps even land on and cautiously tiptoe about. These are mind-blowingly huge numbers…

So, given the enormity of the number of planets in the galaxy, the question Caleb Scharf tries to answer in his essay is: Are We Alone?
