1) I explained to you why you can't be right regarding your assumption of an absolute separation between objective and subjective reality. There's an entire logical principle dating back to the ancient Greeks (and likely before them) that states exactly this...it's the principle that states differences arise from sameness and similarities. Your methodology to forming conclusions about reality incorporates a false assumption about reality itself. Reality includes both subjectivity and objectivity, and so a comprehensive model of reality must explain how each defines the other.
I think my model is much simpler. Basically, we assume that reality is objective, and we, as an objective species existing in that reality, subjectively percieve that reality through our senses. If you start with the assumption that reality is objective, i.e. it exists and is as it is whether we percieve it or not, and place the fault of subjectivity only on our own limited subjective senses and reasoning ability, all the logic falls into place just fine.
Everything shares a fundamental identity with everything else. In mathematics, this fundamental identity is a distributive property represented by the number '1'. Consider a statement, "ab = xy". This is really 1(a)1(b) = 1(x)1(y). The property of identity is a mathematical law that distributes to everything. Everything is united by this principle of identity...of cohesion.
That doesn't actually say anything. All you did was present a set of mathematical symbols, and claim that these symbols represent what you say they do. I don't even know if you mean a * b or something else, or if you mean 1 * a * 1 * b or 1-of-a * 1-of-b. Like, is 1 a number that is multiplied by other variables, or is 1 a function, like
f in
f(x)? If you're going to throw terms like these around, please take the time to explain them, since otherwise they don't have any meeting to anyone but yourself.
2a) You can reason about what's behind the horizon in a probabilistic way, but that's another way of saying "I don't know." Instead, I can say "I know that it's impossible to know what's beyond the horizon" and be correct. You never know where Dank is having his million man music festival. It's always just over the horizon, isn't it?
Actually, it's not "I don't know," but rather "It is not x" and possibly "It is Y with a probability of %." For instance, I know Dank, if he ever does, will NOT have his festival in the Marianas Trench, in the vacuum of space, on the moon or the sun, and likely not on top of Mt Everest, the top of the mpountain range in Chile, in the middle of the Sahara, inside of a car or a small shed, or in my house. Or at any number of other things that can not accomodate the requirements of having a concert (such as viable temperatures and sound carying atmosphere). I think that is considerably more precise than simply "I don't know," especially since it lets us to narrow the choices to an overall where we DO know. Like, if I didn't know whether Dank would have his concert in Venue A or in Venue B accross the street from Venue A, I can say with certainty that Dank will have his concert in a specific city that contains both venues. Likewise, I know that Dank will have his concert on Earth, if he actually does have a concert. And hey, that's how science works

2b) Non-sequitur. The reason is because "beyond the horizon" (not-visible) and "horizon" (visible) are localized distributions in spacetime. Your conclusion would only be valid if you're talking about polytheistic gods. A monotheistic god is omnipresent.
If he is supposedly omnipresent, but yet can not be percieved, then...
1) Except you can logically prove that reality cannot
only be objective, and so your assumption is wrong. Furthermore, if by simplicity you mean "conveniently throwing out information that doesn't fit into the method I've selected," then I agree with you. I'm trying to tell you that there's other kinds of information that isn't empirical information, and while you've acknowledged that this other kind of information is real to some extent, you give its significance no inclusion whatsoever in your interpretation of reality.
That being said, using an empirical model is extremely practical for many things. But it's entirely useless for forming theories about other kinds of information. I'm inclined to think that your refusal to incorporate the significance of this 'other' kind of information is why you ultimately reject any concept of God. It would never make sense to call anything 'God' in a strictly empirical model, especially when empiricism is limited by not only the problem of induction, but also by size (can't observe quantum-scale or global-scale) and rarity (UFOs, ET's, etc.).
2) I provided one example out of an infinite number of examples I could have chosen. Here, I'll do three more:
a - a = 0 is really (1)a - (1)a = (1)0
1 + 2 = 3 is really (1)1 + (1)2 = (1)3
"Apple" is really (1)Apple
Yes, you actually can do this with math, and yes, it actually can teach you something. In this instance, math shows us that "1" is analogous to a distributive property of identity. This is interesting because it shows that for anything to exist in a mathematical landscape, each thing has a characteristic that is shared by every other.
To learn more, I suggest thinking about some more interesting number relationships. Of particular interest to me, aside from the number '1', are 'zero' and 'infinity'. Take 'infinity' for instance. Since 'infinite' represents a sum but literally means "not-finite," it's obvious that some infinities can be larger than others. Consider the following scenario:
"Hey Bob, I like your...yard."
"Oh yeah? How big do you think it is?"
"I don't know, but it looks HUGE! You know how big mine is?"
"Not sure, but definitely smaller than mine."
"

"
And there you have it. Obvious proof that some infinities are bigger than others. And can you believe that the mathematical proof of this was touted as a huge breakthrough? Give me a break. Philosophers have the one-up on scientists and mathematicians all-day everyday (because it's the only academic discipline that is comprehensive enough to include the tools of both the scientist and the mathematician).
3) Ascribing a probability to an event is akin to saying "I don't know." Knowing that you can't know is still knowing. It also makes for a better surprise.
4) If you were a microbe on an elephant's butt, would you know that the ground you're walking on is an elephant?
