A supernatural being that is the source of living things.
Source of life then, right?
From whom all life came?
I don't see how science has 'killed' that Being. Science can show us the physical means (or at least hypothesis or theorize as to that, which is all there is at the moment and which theories do change); or the process... which could be the sole means (though that makes no sense to me, but I digress)... or the means with which a Creator created. The 'details' so to speak.
Faith in God is dependent upon things other than that. Else that would be a god of the gaps, and science might be something for someone to fear (as some do). But there really is no need to fear anything. Science and God are not in conflict. Only our (lack of) knowledge of one or both, are ever in conflict.
