This argument is known as God of the Gaps [0] and it has serious logical and theological flaws.
> Detractors argue that this perspective is problematic as it seems to rely on gaps in human understanding and ignorance to make its case for the existence of God. As scientific knowledge continues to advance, these gaps tend to shrink, potentially weakening the argument for God's existence. Critics contend that such an approach can undermine religious beliefs by suggesting that God only operates in the unexplained areas of our understanding, leaving little room for divine involvement in a comprehensive and coherent worldview.
