I can see that you do not understand how one tests a theory. Events leave evidence. That the event occurred can be confirmed by seeing if the observed evidence agrees with the theory. To have a theory it must be testable. That means that there are possible results from a test that would tell us that the theory is wrong. Theories are tested again and again because even though they can be confirmed in test after test it does not mean that we are absolutely sure that it is right, but as we keep shutting down avenues where it could be wrong our confidence in that theory keeps increasing. The theory of evolution has been tested and confirmed hundred of thousands if not millions of times. Sometimes those tests cause small adjustments to the theory, but they have never come close to refuting it.
And yes, the abiogenesis event cannot be repeated in the lab. One reason is that there appear to be multiple pathways to first life. Aspects of abiogenesis have been confirmed, but an overarching single pathway may never be. The problem for creationists is that their claim of it being impossible has been pretty much been shown to be wrong.
The main point that you seem to be missing is that events do not need to be repeatable to test them. The scientific method does not require that. It is the tests of the event that need to repeatable.
I do not think that you understand what I am saying. Either I am not being clear enough or you do not understand the foundation of scientific thought.
Science is a belief system in that a scientist believes that observations in space time will yield truth statements regarding that space time.
I do not hold to that scientific belief system, I do not believe that observations in space time. Will deliver anything but an ever increasing need for ever more observations and more testing. It is a never ending loop that never really answers the simple questions.
Here is a simple question.
How many stars in the sky?
We are at over two trillion stars and still counting. Will we ever know how many stars are in the sky?
Probably not.
A simple scientific question that cannot be answered.
Here is another simple question.
What is in the center of the earth?
Well we don't really know because we cannot observe it and we cannot use equipment to detect it's structure.
Science will get funding for military research in an abundance, and for medical research because that returns an enormous profit.
Where there is no financial gain from a scientific research then the funding will be non existent.
So we are not really talking about science in a strict ideal sense, rather a commercial form of science.
I really see science as a destructive discipline.
Science ultimately will be responsible for the extinction of life, whether it be nuclear, global warming, a population that exceeds the planets ability to sustain it, e.t.c.
