take the phenomena of miracles for example, which some of the established religions assert as factual , and which have no scientific explanation by the very nature of it being outside of human constraints.... It is what it is , and by trying to always trace a scientific link, some believers might call that lacking faith.
I don't consider myself religious anymore.
I do acknowledge that miracles do happen.
Most miracles are accounted after the fact, in other words, they don't happen while a means of recording and testing is available and in use.
However, miracles happen that have a profound effect on someone's life.
It doesn't matter if there is a scientific explanation when the result is easily measured in a change of the nature of those involved.
Whether the miracle is reality, a delusion or interpretation is not significant for it to be what is considered a miracle.
