I’ve always believed the universe is teeming with life, based on the fact that nothing in the observable universe happens just once.
From top to bottom, macro to micro, nothing in the universe happens once. There’s not just one galaxy, there are (minimum) hundreds of billions, if not trillions, of galaxies. And in those galaxies there’s not just one star, but hundreds of billions or trillions of stars, surrounded by literally innumerable planets. Irrefutable proof that nothing happens just once.
And on our planet life has taken many, many diverse forms, again from macro to micro, and multiple times. All spawned from the same universe that never creates anything just once. It’s impossible, in my mind, to believe the same pattern hasn’t happened countless times across the universe.
My belief is, if all that’s true, in some way everything in the universe is as it is to support life on this one planet. Perhaps in ways we don’t understand galaxies light years away do play a role in that.
Pompous little species, aren't we.
