To thief:
I seriously you really need to read and understand these definitions (do some researches) before you can debate on them.
I usually don't recommend Wikipedia pages, but you should read up on
scientific evidence,
hypothesis,
scientific theory,
mathematical proof,
falsifiability,
scientific method.
Here, in the introduction to Scientific Method, is something that you should consider.
Scientific method said:
The
scientific method is a body of
techniques for investigating
phenomena, acquiring new
knowledge, or correcting and integrating previous knowledge.
[1] To be termed scientific, a method of inquiry must be based on
empirical and
measurable evidence subject to specific principles of reasoning.
Scientific method said:
The chief characteristic which distinguishes the scientific method from other methods of
acquiring knowledge is that scientists seek to let
reality speak for itself, supporting a theory when a theory's predictions are confirmed and challenging a theory when its predictions prove
false
The idea of Scientific Method is to acquire information or knowledge, objectively, in which empirical evidences play a role that the empirical evidences either confirm the hypothesis to be true or shown to be false.
Hypothesis is false, until it is proven true, through observation or experimentation. In experimentation, it has to be tested repeatedly.
You can't test it once or twice, and say this hypothesis is true.
If experiment has been done 50 times, for example, and it only meet the requirement of the hypothesis' prediction only once, then that one successful test must be an error or a fluke. And if your peers, tested your hypothesis, 50 times, and they all failed, then it is a very high probability that your hypothesis is false. At this point, the hypothesis have been refuted or debunked, so it really should be discarded.
A successful hypothesis will develop, to become a scientific theory, an accepted and well-substantiated explanation because it followed the guideline of Scientific Method, and that it frequently and repeatedly confirmed through observations and experimentation.
In science, you can only draw your conclusion to be true, if the evidences support your hypothesis or theory.
Since you can't prove the existence of god (or gods for some other people), because there are no evidences to support his existence.
You keep saying "spirit first" or "spirit before substance", but this is only matter of your faith, belief or opinion. If you and I can't test your belief, then it is nothing more than just that - your belief and opinion.
And other parts of the bible, where miracles occurred. Miracles that defy the law of nature. How do test claims of miracles? Can you prove that it is possible to walk on water, like Jesus?
If the miracle can't be tested, then it is unfalsifiable (meaning unscientific).
There are, I don't know how many evidences, that support Darwin's Natural Selection (not the origin of 1st life).
Creationists tried to replace evolution with Intelligent Design (ID). But ID cannot prove the existence of Intelligent Designer any more than they can prove Creator. ID advocates failed to provide any evidence to support the existence of a Designer.
