Claims of the miraculous do not have objective verifiable evidence that may be consistently verified, and most claims are by those with a religious agenda.
Every miracle is in context of faith. Making it a "religious agenda" is a twisted viewpoint in and of itself.
As far as "consistently verified". That is absurd. Do you have another accident where someone dies and there is a baby in the car in the water to see if it happens again? Obviously not. In that there were "multiple statements" by different people saying they heard a voice, it is consistently verified and therefore a miracle.
I disagree with your opinionNo, the spiritual is spiritual not of this physical world and a different realm of existence. The problem with miracles is the claim and justification from the human perspective.
