You are presuming that this material universe is a closed entity of cause and effect.
It certainly seems that way, thank goodness: if it weren't then we would be living in a chaotic and completely unpredictable universe.
The reality is that there is substantial evidence for causes to be invoked from outside this closed entity in the form of human will and God's will whose origins cannot be understood or explained from within the observed laws of material behaviour within our universe.
Don't be silly: there is no such evidence. Moreover, and to compound your silliness, if your theory is that there are aspects that "
cannot be understood or explained from within the observed laws of material behaviour within our universe" then on what basis could you cite reliable evidence for these if you have not "understood or explained" what you have proposed?
You cannot fully understand the workings of the human mind from a materialistic perspective.
Maybe not, since we don't know everything: but we do know enough to understand that the universe appears to be deterministic and that there is zero reliable evidence for superstitions involving supernatural agents at large - the fevered ramblings of the chronically religious isn't reliable evidence. Ironically though - that they are chronically religious is a characteristic of some people, and therefore is no more than just their particular biology at work and that is no more relevant than, say, that some people have food fads, or a liking for certain types of music or have a fondness for certain sports: religiosity seems just like any other personal trait.
In my view I can dismiss religion as having no personal relevance for as easily as I can avoid watching any form of dancing (which to me is utterly boring and not in the least entertaining) but then I do love motorcycling (though others may not). You see, Alan, you shouldn't conclude that what floats your boat also floats everyone else's boat too - that would be naive in the extreme.
Our ability to consciously apply our will within this material universe is evidenced throughout the history of mankind. We are not controlled by past events - we are in control of our own destiny.
It just seems that way to you, Alan, but if you think more deeply you'd realise that your conclusions are too simplistic.
