The world, being sensible, cannot be eternal, and must have been created by God.

Context

“Then Timaeus, who is a Pythagorean astronomer, preceeds to tell the history of the world down to the creation of man. What he says is, in outline, as follows. What is unchanging is apprehended by intelligence and reason; what is changing is apprehended by opinion. The world, being sensible, cannot be eternal, and must have been created by God. Since God is good, he made the world after the pattern of the eternal; being without jealousy, he wanted everything as like himself as possible. “God desired that all things should be good, and nothing bad, as far as possible.”” source
