Why?!
Think about this: take a look at any one of those colorful, oval "smudges", within the image, and enlarge it, to its maximum, reasonable resolution and magnification on your device.
Each one of the "oval smudges", is a galaxy of stars - just like our Milky Way galaxy!
Our galaxy contains, roughly, 300,500,000,000 stars, including our sun ("Sol") - a typical, standard, type G2, yellow-dwarf star - the kind of star that are a dime a dozen in any spiral galaxy.

Each one of the galaxies in the image also contains a comparable number of stars, planets, comets, asteroids, silicate and metallic specks of dust, and various, volatile gases.
Who knows?? -- how many other beings, in how many other galaxies, hosting, how many other suns, that have, how many other planets in orbit around them -- that, accommodate living beings, just like planet Earth -- just, might be looking right back at us!
THAT'S why!?!
