I suppose it depends on how you mean this. In one sense, it’s a tautology, but philosophically uninteresting. The initial conditions, which were the laws of physics acting within the universe, led to the emergence of life. In any possible world where life occurred, this would be the case.
Saying we could only find ourselves in universe that supports our existence sounds like its offering an explanation but it’s really hinting at multiverse which then becomes yet another necessary factor in our existence. Multiverse is predicated on the belief the universe was caused unintentionally by natural forces. Its not a coincidence that many of the scientists claiming we live in a multiverse are also atheists. Martin Rees is a highly acclaimed astronomer who wrote the book, ‘Just Six Numbers’ in which he concludes there are an unlimited number of variable universes. Here are some of the numbers.
cosmological constant: tuned to 1 part in 10¹²⁰
initial entropy: tuned to 1 in 10^(10¹²³)
strong nuclear force: tuned to ~1%
electromagnetic force: tuned to ~1%
proton/electron mass ratio: must be precise for chemistry
density fluctuations: tuned to 10⁻⁵
dark matter ratio: must allow galaxy formation
Those constants make a big splash because of how narrow they are however there are many brute factors which have to occur. The universe didn’t come with the ingredients necessary for life such as oxygen, nitrogen, carbon, sulfur, phosphorous or rocky planets. That is the result of nucleosynthesis in which simpler matter being blasted by a supernova turns into the complex matter necessary for life. This only occurs due to quantum tunneling which causes stars to ignite and all the laws of physics that causes stars to exist in the first place.
Still that’s not good enough. If the new matter isn’t contained in a galaxy it drifts into interstellar space it won’t get swept up by a star like the sun. Galaxies should spin themselves apart but once again mother nature has our back and came with copious amounts of dark matter that holds galaxies together. Every conditions necessary for life obtained, every condition that would negate life was avoided. These are the kinds of things we look for if we suspect agency is involved.
The claim we can only observe ourselves in a universe that causes our existence doesn’t explain why the conditions for our existence obtained. Its like saying of course you live on a planet with oxygen you wouldn’t be there otherwise. That’s true but doesn’t explain why oxygen exists.
As a consequence given what we know now I see three possibilities.
- They are brute facts. The universe for no reason has these laws and that were caused unintentionally and they just happen to be what was necessary for life.
- We exist in one of an infinitude of variable universes and given the # of attempts a universe with the physics and conditions for life inevitably came to be.
- The laws of physics, the properties of matter were intentionally caused for life to exist.
I think #1 and #2 are chosen primarily as alternates to #3. If we’re seeking an explanation as to our existence #1 isn’t it. Its an assertion that things just happen to be as they are so forget about it and get on with your lives. Given all the things that have to go right and to the degree they have to go right I don’t discard #1 as possible just highly improbable.
#2 is more plausible and has explanatory power. However it carries a lot of baggage. First it asserts yet another condition that has to occur for life to exist, the existence of infinitude of variable universes. This doesn’t make the existence of life simpler it makes it more complex. We have to invoke some unknown mechanism existing outside of our universe and laws of physics because those are the things it allegedly creates. To me multiverse is the ultimate time and chance, naturalism in the gaps of our understanding invoked as an alternative to #3.
The explanation something was intentionally caused is a proven viable explanation. The best explanation for something as relatively simple (compared to the universe and life) as Stonehenge is that it was intentionally caused. Even if we couldn’t trace Stonehenge back to intelligent intervention we’d still see strong indications of design that would lead to the claim it was intentionally caused. Some argue the addition of an intelligent agent adds a greater level of complexity. I’m not sure about that. I think an infinitude of universes and the natural device that causes variable universe is more complex.
