I think it's remarkable that one can't help but use language like 'designed' when referring to highly ordered and complex engineering marvels in nature but what they actually mean is that they believe this robust, highly ordered information management system was haphazardly built one bitflip at a time until we have the most successful organism in the known universe.

The further we push the boundaries of what we know about engineering, the more far fetched that paradigm becomes. I predict that mankind will see more successful breakthroughs when they start looking at organic systems through the lens of deliberate system design rather than spending so long kidding ourselves that it was all achieved by chance against impossible odds.

I think the way evolution operates is quite a bit more complicated than "one bitflip at a time". The way evolution operates is a meta-process that itself was shaped by an evolutionary process which took place (mostly) long ago.

IMO, the genome is like an abstract system which was "designed" for evolution. It can move in one direction or another on the phenotypic plane actually extremely quickly under strong environmental pressures (on the order of only a few hundred or thousand years). And the winds of environmental pressures are frequently shifting, producing what was likely a very thorough and aggressive search of the state space.

I agree there is probably a lot to be learned from further study of the human body and brain, but we will have to re-invent a lot ourselves too since the machine capabilities we are looking for are really a lot different than the constraints that humans were shaped under.

We have an environmental adaptation system which records state, replicates data with efficient parsing, integrity checking and hot / cool storage.

Even the behaviour that most people call 'evolution' relies on our genetic information system.

We have never in our history, ever, seen a system work with such and so many deliberate intentions in managing encoded information that wasn't the product of deliberate intention.

The burden of proof is on those who say that the work of all the software engineers on this website could all be done if you just leave a computer on for enough time. By this logic, the computer left alone will design its own hardware and supply chain, its own OS, its own backup system too, etc etc.

We create systems, we know enough about them to know how hard they are to maintain. And how much effort it takes to create a working system. Even a python hello world is built on >thousands of hours of software engineering. Why should something like the cell be considered any differently?

The universe is so utterly vast that there's enough interactions over billions of years that the likelihood of not life is less then that of life.

You're quite welcome to believe that, but that doesn't satisfyingly account for entropy.

Also, the longer any complex but lifeless structure in that scenario exists, the more likely it is to be destroyed by natural forces that we know and operate with every day.

It's not likely, in fact, it takes more faith to believe in those odds than it does to believe that humans are the deliberately engineered.

you can calculate the odds of life arising from interactions in the universe. you can't do that for some extra-universal being, constant across time and space, creating life on their fancy. i suppose you could if you are trying to estimate the likelihood that the universe is a simulation and you assume the simulation is somehow driven by some intelligent force that set the initial and boundary conditions of the universe.

Science has no agreed consensus on what the definition of 'life' is. If we can't agree on its definition, how can we accurately calculate the odds of it arising ab initio?

Also, your second point is the wrong question being asked. The first is "how likely is it that life arose by chance in a lifeless universe?" The second should be "how likely is it that this ordered and organised system in front of me is the product of engineering and intelligence?"

Based on what we know about information management systems, it's extremely likely that any information management system that we stumble across is the product of intelligence and intention.
