in the second sentence the "because" is not ME implying causation i.e. i think a miracle happened, it is part of the scenario being presented.
it is not saying that i believe in "miracles".
no.
using that example, i would flag your use of "because" not because you believe "a miracle" as an
event "turned a cat into a dog". my argument is that by saying “because of a miracle,” you’re treating miracles as
something that could cause that transformation. the issue isn’t your belief in miracles — it’s that your phrasing assumes miracles have that kind of
causal power in the first place. “If cats were dogs” is a neutral hypothetical adding “because of a miracle” makes it a claim about what miracles can do not about the "hypothetical" event.
it is in fact implying causation.
just not in the way you perceived it to be.
it is me using the conditional of a commonly held position.
and I see this is your stumbling block.
see above.
