In the interest of saving space on here, I won't quote your response.
I agree 100% with the observability issues. There is a potential (however small) that a large number of electrons in the atoms which form me exist in a location millions of light years away. It is only until those electrons (or the energy waves)are observed that the potential coalesces into what we discern as reality. (Ie. all the electrons are circling the nucleus according to the atomic models) This is another interesting facet of quantum physics. You can impart an energy on a subatomic particle such as reversing it's charge and cause an effect on its "linked" particle regardless of the distance which separates them. It could be light years away.
Another aspect of this is that it is impossible to observe something in space and time at the same time. I don't know if I can explain that adequately here so I'm not going to try.
As for the possibility of us all being gods or god-like. I do believe that we were created in the image of God. I think the word "image" is one that is open for interpretation. I do not believe that we are the physical image of God. I also believe that God dwells within each one of us regardless of our faith or lack of it. One of the things that those who do not believe in God or Jesus use as an example to defend the lack of faith is the fact that throughout time there are numerous "messiah" stories and creation stories across cultures separated by time and location. I personally believe that this is evidence of a creator. I believe that humans were imparted with a knowledge of God and it is no coincidence that so many of the stories are so similar. As for us being Gods ourselves, that's where I personally feel it's a stretch. I believe that God is all knowing. While the human species will advance and gain more knowledge, I don't believe we will ever come close to being all knowing.
On a side note, there is a group who believe that since everything is made up of energy including us, there is a "collective" knowledge or energy which transcends time and space. The thought is that since we are energy, we can train ourselves to tap into this collective knowledge and become god-like. It is their belief that this collective energy is God. It's definitely interesting to contemplate.
Anyone can feel free to slam any statements I've made here as I am aware that I do not have a PhD in quantum physics.
