Why wouldn't it be a beginning in the sense needed for the First Cause Argument?
This has nothing to do with the North Pole. I'm not talking about the beginning of the surface of the Earth. I'm talking about the beginning of the Earth as a whole.
The point is that the surface of the earth is an analogy for the way general relativity treats space-time. Time doesn't 'flow' (there is no universal 'now', or any other universal moment of simultaneity, even in special relativity). Time is a direction (actually an observer dependant direction) through the manifold like south is a direction along the surface of the earth. Since there is no other concept of time that applies, the idea that it (the manifold) had a beginning (in the sense that the surface of the earth had a beginning because it is embedded in space-time) doesn't make sense.
The inflation theory still uses the 13.8 billion year age of the universe. You've quoted that same piece a few times now. I don't want you to feel like you are just repeating yourself. Do you have reason to accept him as representing the main theory of science?
13.8 billion years ago is as far as our current theories take us, then we know that they don't work because we'd need a theory that combines quantum effects with general relativity which we don't have. I'm aware of this from multiple sources. Matt Strassler is a working physicist who also writes an accessible blog for the public, so is convenient. The problem with many pop science sources (especially short web pages) is that many of the authors (as Strassler says) have got the idea of a singularity stuck in their minds.
However, if you read many more carefully, some do point out the problem, even wiki has this:
"The Planck epoch is an era in traditional (non-inflationary) Big Bang cosmology immediately after the event which began the known universe. During this epoch, the temperature and average energies within the universe were so high that everyday subatomic particles could not form, and even the four fundamental forces that shape the universe — gravitation, electromagnetism, the weak nuclear force, and the strong nuclear force — were combined and formed one fundamental force. Little is understood about physics at this temperature; different hypotheses propose different scenarios. Traditional big bang cosmology predicts a gravitational singularity before this time, but this theory relies on the theory of general relativity, which is thought to break down for this epoch due to quantum effects.
In inflationary models of cosmology, times before the end of inflation (roughly 10^−32 seconds after the Big Bang) do not follow the same timeline as in traditional big bang cosmology. Models that aim to describe the universe and physics during the Planck epoch are generally speculative and fall under the umbrella of "New Physics". Examples include the Hartle–Hawking initial state, string theory landscape, string gas cosmology, and the ekpyrotic universe."

Is it your assertion that the truth of the premises is unattainable?
I'm saying they are currently unknown and that we have very good reasons to doubt them (as myself and others have pointed out).
This is a statement that you can't simply make. You really would need to prove that.
The premises are about the nature of the universe and causality, so in the domain of science, so you're never going to get absolute proof. What we do have is evidence that suggests they are, at best, highly questionable.
