Yes, you can call it anything you want, even a Flying Spaghetti Monster, it's just a label or shortcut for "Creator of the Universe(s)", so that I don't have to repeat that whole phrase in the rest of the argument.
But it is important to substitute the definition back when we conclude the argument. Which is:
Creator of the Universe(s) exists in reality.
If you refuse the idea of creator at all, then you will face contradiction the minute you create something in your imagination...
Here is where it totally falls appart for me. I can't see how "creating something in your imagination" is actually creating anything at all. It's just imagination, which happens through a mechanical/physical process. If I change some electrons on a tiny slab of silicon, and the computer "imagines" the result as a picture of a house on a computer screen, the computer didn't actually "create" a house. It's just an asembly of electrons into a pattern that can be interpreted as a house. Same with our imagination - we aren't creating worlds, we are just rearranging electrons in a way that let our brains interpret them as a representation of something.
And by the way we didn't witness it, we reconstructed it in our imagination, based on some experimental data from the satelites, but there is no certainty, that this particular reconstruction is unique.
That's the thing, we have witnessed it. We gathered some experimental data from satelites, and used our imagination and knowledge of math and physics to construct a model. The model stated that the universe popped into existence, containing equal parts matter and antimatter, so that the "matter can not be created or destroyed" law still applied, which it does, since the sum of all universe cancels each other out to 0. We confirmed part of that by observing the motions of stars and galaxies, and seeing that the matter was balanced by dark matter we can't see. Then we expanded on the "popping into existence" theory by using updated physics models to predict that such an event can happen spontaneously, on it's own. And finally, when we ran the Large Hadron Collider, we actually saw such an occurence happen many times, where tiny particles would pop into existence, containing both matter and antimatter. Essentially we saw tiny big bangs, except they were very little banks, and, having popped into our own already existing universe, quickly burned out or were annihalated. This confirmed that an event such as a universe popping into existence was not only possible, but probable. Oh, P.S. that's also how we generate anti-matter at this point: we made lots of these little pops happen, then separate matter from antimatter using magnetic fields. That's how it was done in Dan Brown's Angels and Demons, too.
Where are you getting two singularities from? It was just one single quantum "pop."
The one is the emergence of physical universe, the other is the emergence of you. You have agreed, that there was no pre-existing idea of you 1 year before your birth in this universe, so your emergence in it is a singularity.
But my being formed through chemical processes isn't a singularity. There was no pre-existing idea of my car 5 years ago, either, but it was put together from raw materials, and now here it is. I don't call that a singularity, I cann it a normal physical event.
The inconsistency in your reasoning, is that you require (for no obvious reasons) first singularity (the universe) to occur first in order for second singularity (you) to follow.
It's inconsiistend to reason that an environment of physical laws and raw materials needs to pop into existance, before those physical laws and raw materials can be used to put something together?
Singularity already means, that you cannot coherently explain how it occurs, therefore requiring something else as a prerequisite seems unfounded.
If that is your definition of a singularity, then neither the Big Bang, nor my formation, were singularities, since we can coherently explain how both happened.
There is another good argument to think of "you" as a primary (and maybe only) singularity. There are two possibilities - one is that physical universe exists and you perceive it, and the other is that physical universe is just an elaborate product of your imagination. Out of these two possibilities physical universe exists only in one case, while you exist in both.
Why is it relevant which one of these two is true? If there is no difference in the way I percieve the universe from either of those cases, then it makes no difference as to whether one is true and one is false. I will still come to the same conclusions, based on my own observations and experiences. It's like believing that there is a god, but that he is unable to interract with this world in any way. In either of those scenarios, the easiest and most productive outcome for research is the one that ignores the untestable and unprovable (all in my imagination, or an untouchable god), and only focus on things that may affect reality, however we may percieve it.
As to the perpetual motion machines, I have always wondered if simple hydrogen atom is a good model for that. Will the electron ever run out of juice, if the atom left alone indefinitely? What about permanent magnets, where spins of those "perpetual" electrons are aligned and therefore can be used to pull things?
Electrons aren't spinning, they are in a cloud around the protom, existing in quantum state, i.e. everywhere in the cloud at once. You can pull a limited amount of energy out of them, but it's like extracting energy out of a spring: all you are doing is changing the hydrogen atop, and it will "snap" back, releasing the energy, as soon as you let go. Ditto for magnets. It's not mystical energy, it's just potential and kinnetic energy. When you pull two magnets appart, you are using kinnetic energy to store potential energy between them. When they come back together, they take their stored potential energy and releasse it as kinnetic to snap back together. Magnets are about as full of mystical energy as mattress springs, and as effective. All "pulls" will always end up at a point where there is nowhere else to pull to...
