Definition
A basic definition of God is as the Creator of the Universe.
The Creator can further be defined using theoretical probability by considering its roots:
Outside of the limits of Time and Space, the laws of physics and science do not apply.
Therefore, outside of time and space, any number of infinite possibilities can exist.
According to Chaos Theory there is in fact an underlying form of order within seeming chaos.
In infinity, this order will have an infinite amount of time and space to coalesce into a form of perfect order, or perfection given form.
In theory, perfect or complete perfection would reach a point of sentience and intelligent existence. Assuming such perfection is based on order, such would be benevolence incarnate.
Hence we now have an intelligent being of perfect benevolence, capable of doing anything in infinite probability.
This can be considered God or the Creator.
Now why this being would create the universe is another matter:
The Universe is a creation of immense complexity and diversity. This can be explained by the idea that a perfect form of benevolence would want to bring order into the remaining chaos.
Thus, God creates the foundations upon which the universe is ordered and maintained, which we have discovered as the scientific laws of physics. These basic universal principles are absolutes that can only be manipulated outside of the realm of time and space.
The universe is God's method of communicating benevolence.
The reason why the universe isn't perfect is that perfection cannot be achieved without disrupting the limits that govern the universe and make it able to be manipulated. There are other reasons as well concerning the limits of probability in limited time and space.
Now the existence of Humans is of particular interest:
Humans were created as companions with whom God could share existence with as an extension of God's benevolence. As part of this benevolence, God gave us an extraordinary power: Free Will.
Free Will enables us to choose our destiny and to give us complete freedom, which is part of God's extension of benevolence.
This is why God can control our destiny, while we can still choose what we want our destiny to be.
The creator plans out the creation to its fullest extent and attempts to achieve the most positive and benevolent outcome for everything as a whole.
The reason why people suffer is so that in the long run, Humanity will learn from its mistakes and the challenges set before us, and eventually achieve its greatest outcome possible.
By restraining our freedom, God would in effect be causing more evil by enslaving us, rather than allowing us to choose to do good or evil.
The concept of omniscience, or the characteristic of being all-knowing, is characterized in God as the ability to instantaneously experience all points in time, at all positions in space, simultaneously, as a consequence of existing beyond the four known dimensions of space and time.
Omnipotence, or the characteristic of being all-powerful, is a result of existing in N-Dimensions, or infinite or zero dimensions, and therefore, being able to manipulate space and time, to cause anything with a probability greater than zero to occur. Thermodynamics deals with changes in energy. However, omnipotence has nothing to do with introducing energy into a system, rather it is the manipulation of probability and apparent randomness to bring about intended results.
Inversely, if an entity were to exist that was able to perceive all perceptions, eventually culminating in all information in reality, this would have effect of making this entity all powerful, due to the fact that complete information would including knowing how to cause anything to occur, or prevent anything from happening.
Omniscience therefore leads to omnipotence, and vice versa, to be all powerful would enable an entity to gather all information at will.
Benevolence comes from the knowledge that such an entity would possess being perfect, granting it the only authority to make moral judgments, since it has felt every intent, every hurt from wrongdoing, and thus can see all sides of every morally concerning incident. Such an entity knows how you felt when you were hit, and how the person hitting you felt when they threw the punch, so to speak.
Absolute awareness of everyone’s fears, desires, pleasures and sufferings would likely cause this entity to seek to reduce the sum of suffering in the universe, in order to reduce its own distress. Thus, God most likely functions under a Super Utilitarian morality, one that is willing to allow smaller amounts of stress or pain for long term happiness of the greater whole.
