If there isn’t a multiverse, our universe is unique:

Recently a friend convinced me to go see the new Spider-Man movie, where I was surprised to see that the multiverse not only makes an appearance but plays a crucial role in the plot. Without giving away any spoilers, Benedict Cumberbatch’s character, Doctor Strange, declares, “The multiverse is a concept about which we know frighteningly little.” He’s right. And that’s part of the problem for materialists who cite the multiverse to explain.Casey Luskin, “Spider-Man, the Multiverse, and Intelligent Design” at Evolution News and Science Today (January 4, 2022)
Luskin list the conditions, then says
Apparently under the Newspeak of materialism, proposing an infinite ensemble of universes that we can’t observe is the “simplest” explanation. Some authorities feel otherwise — noting that the multiverse is not a “simple” explanation at all.
Ockham’s razor is a logical principle, often used by scientists, that holds that the simplest explanation tends to be the correct one. What is the simplest explanation: (1) that the fine-tuning of the universe is the result of a near-infinite number of unobservable universes spawned by an unknown mechanism of unexplained origin, or (2) that the special, life-friendly conditions of our cosmos are the result of intelligent design? Theoretical physicist Sabine Hossenfelder (no friend of intelligent design) explains that the multiverse is too complex an assumption to survive Ockham’s razor.Casey Luskin, “Spider-Man, the Multiverse, and Intelligent Design” at Evolution News and Science Today (January 4, 2022)
The, multiverse wouldn’t even be considered if there was no need to wonder about our own universe’s unique fitness for life.
