[Andrew66]

God is herein defined by the following characteristics:
An indesructible, maximally powerful and intelligent being.

1) Change is eternal. (if at any time the sum total of existence did not have the potential to change - then we would be "stuck" in a "frozen" state - which clearly isn't the case).
2) Existence has therefore experienced an infinite number of changes of state over an infinite temporal period.
3) By natural selection, beings of varying intelligence, resilience and power have arisen and became extinct.
4) Over an infinite period of time, eventually, an entity will have evolved to a threshold point whereby it became indestructible.
5) It is likely that such an indestructible being is extremely (if not maximally) powerful and intelligent.
6) Such indestructible being meets conditions coincident with what humans have declared as God.

Note, importantly the above argument does not predict necessarily a good or evil God.

Note, the above argument does not necessarily support that such God ever revealed itself to humans.
