I'll explain,
All connected means that life is one organism broken up into different parts due to the nature of the material 3rd dimensional world. In death the energy lives on and passes multi-dimensionally, there is even dark matter which we don't know what it is, and anti-matter. We are even connected to that, just in a way which our perceptions is not capable of seeing. Yet we know the energy is real.
I say we are all connected because everything you do, influences everything else in the universe. Matter is liquid, like water. You are energy because matter is energy, when you do something you are simply changing the configuration of energy in the universe. (This is like making waves in a pond.) Everything you do, every thought you have, every second, you are influecing everything else in the universe. I say there is no seperation because at the core, if we assume the hypothesis is true and that matter is simply a hologram and just real in our brains, the universe is actually energy and forces which we simply do not have the capability to percieve with our physical bodies.
Quantum entanglement has proven that teleportation is possible. If you can teleport something, or do atomic teleportation of objects, this proves there is no such thing as distance.

Our math and science has shown us that just because we cannot percieve something, does not mean it is not real, and that just because we percieve something does not make it the underlying reality.
The science of perception is under developed, the video I posted from Google, discusses perception, and if you can ignore the obviously biased Islamist religious slant, the main portion makes sense. The brain itself is simply a reciever of information, when you look at something the light itself actually never enters your brain, it is just energy from the object. When you talk to someone and you hear their voice, it's their kinetic energy. We are simply energy beings, and we don't really have a good concept of what reality is because we focus on the material end of things.
You and I are connected, we can communicate with each other and influence each other, as we also influence the eco-system, evolution, and forces unseen that we may not even know exist yet. This is cause and effect, energy (you,me,and everything with the ability to have consciousness), was created during the big bang according to our current science, and the energy of the big bang created matter meaning in all likelyhood, energy existed before matter and is another dimension completely, either higher or lower, I don' t have enough knowledge to know, but I know that energy never dies, it just changes. Nothing you do ever goes away, every single action you ever did is stored in the universe forever because your energy flows through all matter in the universe, just as light does, and sound does. As far as we know there is no way ot destroy it, it simply can be transfered into different states, like heat, cold, or fast, slow, or different densities etc.
The brain runs on electricity, and this is a fact. The computer also runs on electricity and that is a fact. You get your energy from eating food, which gets its energy from the sun. You get your water, and food and thats your fuel for your brain, which then goes on trying to figure out how to get more water and food. The brain is so efficient that you have enough time to solve the universe, but it does not change the fact that energy is recycled, therefore time does not really exist except for material organisms. Matter seems to be constantly created as well by energy, so matter is recycled too. Consciousness is the center of it all.
I do not think humans are anything special, it's more of a situation of consciousness being the most special and only thing in the universe, the reality of the universe. Matter only exists because of perception but a blind person still can have consciousness even if they can't see, and it might be limited but it's there. All animals have consciousness, and the more self awareness and perception ability you have the higher your consciousness.
I have too many beliefs to go into details, but the majority are based on science, and you can call it pseudo-science, but science does not fill the void as to what we are and why we exist. Science from a lot of athiest treats us as if we are the void, just accidents of the universe, and are no different from the machine you are typing into on your desktop. I say we can fill the void.
If you want to discuss philosophy and metaphysics we should start another thread. I'm not trying to get into a religious or philosophy debate, I just wanted to show that there is no objective reality and that science is just an attempt to make sense of what we percieve to be real.
