To this, it is responded that inventing a multiverse to explain away apparently purposeful tuning of universal constants doesn’t really work. It’s an excuse.
How would you explain why Earth is at the correct distance from the Sun so that the life can exist here? I would say there are many planets, most of them are in wrong distances, and Earth happens to be one in the right distance, which is why we have this debate here instead of on Pluto. But this is a similar kind of excuse.
It would be even more suspicious excuse if Earth would have a more cloudy atmosphere, so that no one would actually see the sky. And when we can see the sky, it is also suspicious to assume that those tiny dots are actually also Suns, and there is actually a few order of magnitudes more of them than we can see, and they have their own planets that we can’t see at all, etc.
Just saying that there is a precedent that something suspicious things happen to be true.
On the other hand, we do see the stars, we can see other planets through telescope, in other words, these suspicious truths have left some observable footprints. We can even experiment with Everett branches on the microscopic scale. But we have no observable footprint of the Tegmark multiverse. And I am not sure if we ever can have such thing.
However, the whole religious argument is “if you cannot explain to me all the details of the universe right now, you must accept the existence of my invisible friend”, which is nonsense. Not knowing some laws of physics (yet?) is perfectly normal even in universes without invisible friends, so it cannot be used as an evidence for one.
