Different approaches to the understanding of a scripture
Yes. A salient example being the contrast between literalism and non-literalism, allegory, etc. So, different people, when they say they believe what is in a holy book will believe in different things, or different aspects of it, allegorical, literal, mystical, etc.
And if people want to interpret their scriptures as containing scientific miracles then I don't really care. They're entitled to do that, and it's also possible that a book might contain knowledge, scientific or otherwise, that was 'inspired' by a preternatural or non-human intelligence. It's a possibility whether you like it or not, regardless of its apparent likelihood.
What is wrong with the God of the Gaps allusion ??
Nothing aside from the fact that I never mentioned it, but you imputed it to me.
Many people believe in God just because of it, just because they don't know how to explain certain phenomena.
I suppose so yes.
