We know that physical measurements are not perfect in the sense that they are not precise to the last digit. Therefore, one cannot construct a perfect theory from such a measurement.
Therefore a God is supposedly must be Perfect, i.e. omni-whatever cannot exists as real to be verified by physical measurements.
There are two types of perfection for philosophical consideration, i.e.
- 1. Relative perfection
2. Absolute perfection
1. Relative perfection
If one's answers in an objective tests are ALL correct that is a 100% perfect score.
Perfect scores 10/10 or 7/7 used to be given to extra-ordinary performance in diving, gymnastics, skating, and the likes. So perfection from the relative perspective can happen and exist within man-made systems of empirically-based measurements.
2. Absolute perfection
Absolute perfection is an idea, ideal, and it is only a thought that can arise from pure reason and never the empirical at all.
Absolute perfection is an impossibility in the empirical, thus exist only theoretically.
Examples are perfect circle, square, triangle, etc.
Generally, perfection is attributed to God. Any god with less than perfect attributes would be subjected to being inferior to another's god.
As such, God has to be absolutely perfect which is the ontological god, i.e. god is a Being than which no greater can be conceived.
Perfect:
Note the relevant meaning for 'perfect' is;

When I used the term 'absolute perfect' is a double enforcement to the meaning of 'perfection.
Absolute:
- a value or principle which is regarded as universally valid or which may be viewed without relation to other things.
In philosophy (often specifically metaphysics), the absolute, in most common usage, is a perfect, self-sufficient reality that depends upon nothing external to itself.[1] In theology, the term is also used to designate the supreme being.
