@jjww30 When something is unequivocally proven it is called a FACT, not a theory. You need to grasp that concept.
A theory doesn’t need to be proven to be a theory. Most aren’t. What makes something a theory versus a hypothesis is supporting evidence. Hypotheses are ideas, thoughts. Hypotheses are not supported by any evidence. Once some evidentiary support for a hypothesis exists, it becomes a theory. Once you have enough evidence for it to be evident (through the scientific method), it becomes a scientific fact.
You think you’re the best-educated person here… I assure you, given your arguments and suppositions, that you are far from that, especially in physical sciences.
The scientific method dictates this:
Hypothesis -> Theory -> Fact/Fallacy
There is, at this time, more than sufficient evidence for the hypothesis of this mass extinction event for it to be a theory. It is actually the leading theory among many, and for quite a while. Evidence from multiple disciplines supports this (geology, biology, paleontology, oceanography, physics and chemistry to start).
In fact, once the data from this latest finding is verified by peers and published, it will likely make this a scientific fact.
