I don't worship any deities. I'm not even sure what the word 'deity' means.
In other words, how could a human being, with all of our inherent limitations, distinguish deities from hypothetical imposters like super-space aliens?
That was the premise of the movie
Stargate which was so nicely dramatized, I thought. Of course the aliens have to be superior to us to even get here, so that rules out the bacteria that might someday show up on one of the moons of Jupiter, for example. And, as you say, they'd have to jump through something like worm holes unless they basically live forever and have endless supplies of energy. But all of that does jibe with minds of early cultures, at least in some of their ruminations on the subject, made of course in the absence of any evidence to the contrary, and working from the only plausible ideas they could conceive.
How does divinity differ from 'the unknown', apart from our tendency to project human-like moral and psychological characteristics onto whatever we imagine it is?
The element of superstition only recently seems to have come under criticism now that people understand better what facts and evidence are, how to test them, and what the principles of valid logic are. The superstitious mind converts the unknown into something imagined to be true.
I suppose that I have considerable confidence in science. It's the best means that humans currently have for learning about the physical universe that we inhabit. But that confidence isn't unlimited, nor do I believe that it should be. It isn't Christian-style religious faith.
I've never quite understood your reservations. For example, I'd bet you're quite certain that the relationship between a circle's circumference and its diameter is Pi. Science has plenty of these principles which are considered "settled". Maybe you'd be willing to agree to that much. I'm not sure how much more the confidence in science matters. We rely on stuff that works. You don't press the elevator button expecting to go sideways, and you have pretty good reason to believe that as the airplane accelerates on the runway you're going to start feeling some gees, and seeing the ground drop below you. And so on. These things won't change. The only things that change, when they do, are the ways new information adds to the repertoire of facts currently in play. The use of antibiotics is now understood to contribute to the evolution of antimicrobial resistance, for example, so the treatment for an infection has become more complicated. That's a change, but not something that washes away the foundations. It's always possible that some pillar of science will fall, but I can't for the life of me imagine what it might be. So much of nature has been nailed down that it seems highly unlikely.
Our current scientific understanding is a work-in-progress, an approximation, a conceptual model.
I see science as the ruling of a court, made up of the best minds yet to evolve, as to the truth of certain laws or principles of nature, as concluded from exhaustive review of the best evidence available. (Here I'm referring to the level of material found in science textbooks.) Very rarely those rulings are taken up on appeal, when there is new evidence, and something may very rarely be overturned. But more than likely, it just brings a new case, in which a new ruling comes out, specific to the new information. The approximations to truth are usually much better than needed to ascertain a derivative truth. So, for example, if we want to know the true position of the landing spot for the Mars rovers as their guidance systems were sending them there, the approximation to "actual time" were far better than the accuracy of the spacecraft. And still they landed . . .within a few football fields of the intended site? I can't think of examples where approximations mattered that much. Newton's discovery of the Law of Universal Gravitation can be restated as an approximation to General Relativity -- but very few kinds of practical applications need more than a couple of decimal places of accuracy, which Newton' Law usually gives them. Where science seems to be most sensitive to the kind of thing you're talking about is at the leading edge of new discoveries. The equipment needed to refine measurements evolves with the technology, so there's a big factor which drives the accuracy of new discoveries. Most of that seems to be relegated to the past, when experimental scientists often had cobble their own instruments together (Galileo had to grind his own lenses to discover the moons of Jupiter; Tyndall had to make his own calorimeter to measure the heat absorption of CO[sub]2[/sub] in the atmosphere, and the Genome Project had to have a new chip that reads random fragments of DNA and then integrates the fragments using a correlation technology related to cell phone signal processing). That's a huge piece of the work in progress you refer to. But I think it builds a lot more than approximations and conceptual models. To me it's more like exposing the whole remains of a Woolly Mammoth, by first exposing a tooth, then a jaw, then eventually the entire remains, as the scientist carefully removes one grain of sand at a time. The whole of a thing can eventually be known, if the signal is there; and if investigators are lucky enough to land on a large enough signal, then the conclusions can evolve quite rapidly, with good accuracy and with evidence far more tangible than just a conceptual model.
Science doesn't supply us with answers to every problem that we encounter in life. It isn't what gives our lives whatever meaning that they might have.
Technology certainly consumes itself with trying to answer every problem people encounter, but I guess people tend to be very needy, and great inventors of necessity.
So I guess that's an endless well. Another side of this is that science creates a lot of problems for people, through unintended consequences. A lot of patients die from side effects. Planes are great ways to solve our need to travel quickly but they also created a powerful psychological weapon for terrorists. The automobile "brought us so much joy" (one woman with cabin fever once wrote Henry Ford) but this is not the case where triage is being done for victims of traffic accidents. And the vehicles have created a dependency, and from that, a dependency on oil, and from that, pollution, climate change, petro-terrorism and volatile economies.
But as for meaning, these artifacts of human progress seem to me, in the long run, to add meaning. Science can help us live longer which means we have more time for whatever the pursuit of meaning entails. Then there's the opportunities derived from science. Right now, for example, I'm having a moment to reflect on things that give meaning to my own life, which was planted in my mind by way of access to the technology which allowed your post to pop up on my screen. It all depends on what's meaningful to people, but from the sheer universality of the web, it would seem that the communications technology alone has greatly added to the meaning of folks' lives. At least the potential is there. Exploiting it to add meaning it is another thing, I suppose. (Now we just need an app for that.)
For me there is little on Earth that adds more meaning than the kind of material you might find at the Smithsonian, or taking a guided tour with a scientist in the Park Ranger Service at a place like Yellowstone, or say a daylong visit to the Monterey Bay Aquarium. Since sites like these are all provided for public access, they represent another cult within the scientific community than the dry research scientists. At least these folks ingeniously devised ways to take the public by the hand and show them new ways to find meaning in their lives.
Science isn't a beatific vision.
I think a lot of science is founded on ideas much more beatific than, say, a Renaissance painting of the Apotheosis of Jesus. Consider all of the imagery from the Hubble alone, and "beatific" is really the best word to describe it.
