In the same way that you don't know that there are machines that don't have makers.
However, in the vastness of the machine world, the evidence that all machines have makers is so great, that you would have a difficult time finding a machine without a maker.
I'll help you. There is that ancient Greek machine that turns out to be the oldest computer in the world - http://www.pbs.org/wgbh/nova/ancient/ancient-computer.html - that was found on an ancient Greek galleon. Just because it was found there, on a sunken Greek galleon, doesn't mean we know that it had a maker. But try to tell that to any scientist, and they will laugh you right into a funny farm.
This is the same argument as ''everything is designed'' which I already debunked. You told me to look for the definition of machine: ''an apparatus consisting of interrelated parts with separate functions, used in the performance of some kind of work:'' Now if the universe can be a machine, then so can a volcano, for example. Now how do you know a volcano has a maker? We don't. We only know ''machines'' have makers because those makers are humans, all the machines that have makers are humans, that doesn't prove god or that all machines have makers, it only proves, in any case, that all machines have human makers.
Consider AI. It is a machine made by mankind. Yet it can teach itself to play chess better than a human, even in ways that a human can't match. Our crude AI isn't really alive, doesn't really have sentience. Yet it acts in ways that seem uncontrolled... at least as far as we are concerned. But the work that it does is not controlled directly.
AI is a machine made up of many smaller machines, doing work that is not controlled by us directly - not even entirely understood by us. Yet the Master Machine Maker understands every, last erg of energy and force in a volcano, via cause and effect. He set it up. He also understands every last working of our AI. None of this means that He has to focus on all of it all the time, with the essence of His "I AM."
You have in no way debunked the idea that everything is designed. What you are doing is debunki9ng yourself. Soon you will be gone forever... if you do not change and take hold of the offering of eternal life from God.
You didn't answer at all here. I asked you how do you know that everything is designed or made by a sentient being. Yes we know our machines are designed by us, obviously just like we know a watch or a chair is designed by humans because nature does not produce such things. You are claiming that trees, rocks, planets, everything is designed by something else, my question is, how do you know?
Did you forget the complexity already? Our examples of machine making show us that the weaker thinkers among us don't really design the more complex machines. Yet all the machines and "levers" that we make come from nature and examples in nature. Nature, being full of machines that are way more complex than the machines of man, were made by Someone way smarter and more capable than man.
Machines and their complexity and the greatness/intelligence of those who make them is one of the greatest examples that God exists.
Perhaps you fit into my previous post along with VOD.
Did you forget that I already showed you that complexity does not show design? It's right here:
''assumes humans determine whether or not something is designed by seeing if it has an accurate adjustment of parts—that is, if it shows complexity. But this is certainly mistaken. We know that something is designed not by its complexity, or even the degree to which it appears to serve a purpose, but by looking for ways in which it differs from nature. In other words, nature is the benchmark against which we compare an object to see if it is designed.
For example, many naturally occurring rock fragments just happen to have a sharp edge that is well-suited for serving the purpose of chopping meat, though this does not lead us to believe that these fragments were designed. Yet, we have found clearly manufactured prehistoric chopping and cutting stones that were designed. How do we know they were designed and not just examples of fortuitous rock fractures? Clearly it is not because they are sharp, since naturally occurring rocks are also sharp; and not because they are complex, since they have neither parts nor complexity; and not because they serve a purpose, since obviously random events can make a rock very sharp. We know these stone hand axes were designed because they have markings on them that differ from what one would find in nature—that is, they have signs of manufacture.
Because the proper criterion for establishing design is difference from nature, and not complexity or apparent usefulness, we can know that something was designed even when it is both extremely simple and has no identifiable purpose at all. ''
''we don’t know something is intelligently designed because it shows complexity; we know it is designed because it shows signs of manufacture, and the only way we know something is manufactured is by comparing it with nature or by having direct experience of its manufacture. Now, if the criterion for determining design is comparison with nature, then it makes no sense to apply that criterion to nature itself since nature provides the very benchmark for making the comparison.''
Did you notice that all you showed was the writings of someone else who doesn't have anything concrete to back up what he says? Rather, the exact things that he is trying to use to show lack of intelligent design in complexity are the things that uphold intelligent design in complexity.
The argument is simple, how do you know that all complex things require a designer? You claim that complexity shows that everything is designed but how do you know? We only know our things are designed because they are made by us, humans and we know these things are designed by us by comparing them to nature.
This argument, by the way, is a well known flawed argument, discussed plenty of times.
''The argument from design, also known as the teleological argument, is an argument for the existence of God (or life-engineering aliens) that may be summarized as follows: When I see a complex object such as a watch, I know it has been designed: therefore, when I see a complex object such as a tiger, I should infer that it has been designed. This act of comparing two objects and drawing similar conclusions based on similarities (while ignoring important differences) is a prime example of a false analogy.''
