Saying “she built a house” is ordinary and correct, even though she did not create the earth, materials, abilities, or laws of nature from nothing. Likewise “Zayd wrote a letter” attributes the acquired action of writing to Zayd, while the origination of the act's existence is attributed to God.
These comparisons clarify meanings; they do not establish a complete physical mechanism for divine creation and human acquisition. Their value is to separate everyday agency from independent absolute creativity.
Thus human action need not be emptied of meaning, and every craftsperson need not be treated as an independently creating deity.
