That's silly. If my wife's car won't start and I explain that it's out of gas,
really an explanation even if I don't know why it's out of gas. The
definition of an explanation of an event is what you would do to effect or
event. In general there are multiple things you could do and hence multiple
causes of an
event. The image of a causal chain leading back to an ultimate link is
misleading - it is
more like causal chain mail that branches out as you trace it back. But just
can't trace it back to a single ur-cause doesn't nullify my advice to my wife
to put gas
in the tank.

There can in the same way QM explains the decay of unstable nuclei. That's
cosmogonists are searching for.

No, it's not a tautology because there is an underlying theory that explains
nuclei are stable and some aren't and exactly how unstable they are.

Was the conscious experience of knowing the Earth is flat more fundamental and
than the fact that the Earth is spherioidal?

Why do you suppose you have uncaused experiences?

Why do you think this? Maybe I found 121 in a table of prime numbers that was
Maybe a friend told me 121 was prime. Maybe my calculator malfunctioned due

Why would I try to phrase my answer in terms of "the ultimate cause"? Why
would I even
suppose there is such a thing as "the ultimate cause"? And why would the
absence of an
ultimate cause have any relevance to my explanation in terms of proximate
