This can in fact be deduced, albeit rather shakily, if you treat the universe as computable in its entirety. In the Plato-ist worldview, integers exist automatically as constructions of logic; from there, functions exist; and functions describe the universe in its entirety.So, regardless of knowing now why matter exists, we don't know why "something at all" exists rather than "the absence of anything." This finding does not absolutely vindicate atheism; rather it just makes the necessity of a God-like being that much less likely and that much less rational to believe.
