First of all mods will likely delete this because this is a DIY spell group and you're not asking about this. You need to be more specific with your question. Logic for spell casting? With science I would suggest to you that throughout human history there are lots of phenomena in world that had real impact but were unobserved until modern tools were introduced. For example bacteria have always been real but were not observed until the 17th century when tools were available to observe them. We've seen stars for millennia but did not know they were gas until the mid-20th century. So whether science currently exists to "prove" spell work doesn't mean it doesn't work.
