Another God said:
So i don't just talk about falsification points, which is only an idealised version of science IMO.
In an 'eclectic' account of scientific practice (which I prefer) falsification is just one of the methodologies used by current science, far from being decisive; it cannot make a clear demarcation between science and pseudo-science. So even if the requirement of falsifiability is not met this does not automatically mean that we have the right to marginalize a theory, especially if it is otherwise very progressive (and explaining more than its alternatives).
In the case of Natural Selection the idea is that the different parts of the 'net' of accepted scientific knowledge, having methodological naturalism among the basic assumptions, form a very coherent 'compound' with Natural Selection, the different parts of this 'net' support each other indirectly (also the theoretical constructs posited as existing are absolutely necessary to explain the empirical success of the system, basically no redundant parts exist).
This cannot be said currently about the system having hypothesis God / an Intelligent Designer in the place of methodological naturalism but preserving the vast majority of accepted scientific knowledge and a modified evolution theory; here 'God' is a theoretical construct which does not make at the moment potentially testable future predictions in conjunction with other accepted scientific enunciations and it is very difficult to interpret from currently observed facts, unambiguously enough, God's (aliens / multidimensional intelligent creatures) intervention in Nature (the creation of new species included). This (and the fact that all existing 'irreducible complexity' arguments are weak now) is why ID cannot be considered currently on a par with Natural Selection.
Of course from the fact that hypothesis God is ad-hoc, rather redundant and basically non falsifiable does not automatically result that such an alternative system (having God as a basic assumption + the rest of accepted scientific enunciations less natural selection) is false or disproved. We should be rather very cautious here the old problem of epistemological infinite regress is far from being really solved, in a unique manner, once and forever (see
this for example), at most we can say that currently a system based on methodological naturalism has more arguments 'pros' and thus deserves to be, provisionally, at the basis of current science.

"I know the questions in the minds of many of you who have followed me to this point: "Does not science prove that there is no Creator?" Emphatically, science does not prove that!"

"Certainly science has moved forward. But when science progresses, it often opens vaster mysteries to our gaze. Moreover, science frequently discovers that it must abandon or modify what it once believed. Sometimes it ends by accepting what it has previously scorned."

Club: London, 1960, p.5)
"There must be no barriers for freedom of inquiry. There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors." (J. Robert Oppenheimer)
