I can explain stuff to an 8-year old child, but a very long part of my explanation will be about bringing the child "from zero to graduate-level knowledge" in mathematics. The solution to explaining stuff to an 8-year old child is thus not by making the material sufficiently stupid to make it understandable to a typical 8-year old, but to make the 8-year old sufficiently smart and knowledgeable to understand the topic.
