Is it possible that humans wouldn't be able understand the universe just as we all agree a horse can't?
That is to say, is it possible that there is no way to prove theism or atheism? It's just a guess?
To know the limitations of the mind should always have been a part of knowledge. Instead humans presume that any mind can learn anything, the flaw of Adam setting himself alongside God. Even when the human mind learns the results of physics experiments, their concepts are about these experiments, not about the universe in its essence. And, these ideas come into minds that are clearly poorly ordered, unable to dwell free from anger and greed, and with cold and instable relationships even in the family. In general the entire area of metaphysics is blocked to the physically entangled.
