We can look at the usual arguments offered for a Copernican view of the universe (there’s nothing special about Earth or us). For example, the universe has existed for billions of years and is enormously vast. Only it turns out that the universe HAD to be billions of years old for life to be able to exist at all, and it had to be enormously vast (these properties also allow a small window in which we could make the discoveries in physics we have, such as the recent observation of gravitational waves or the CMB that provided such clear empirical support for the big bang theory). We needed a long, long time for the universe to spread out, cool off, produce the basic elements required for life, solar systems with the right distributions, etc. In a very real sense, we are in an extremely special space in the universe on an extraordinarily unique planet at the perfect cosmic time.
“No one should be surprised to find the Universe to be as large as it is. We could not exist in one that was significantly smaller. Moreover, the argument that the Universe should be teeming with civilisations on account of its vastness loses much of its persuasiveness: the Universe has to be as big as it is in order to support just one lonely outpost of life.”
