William Lane Craig continues to desperately defend the indefensible.

For evolution to happen things must change over time, but change over time alone is not evolution, which is the process theorised to explain the arrival of complex life from the most simple.

Um, change over time is how simple life diversified to become more complex. Evolution, as it was initially discovered, was based on observations of organisms changing over time, which had implications about the diversity of life, but it wasn't theorized to explain the diversity of life from a common origin, that just happened to be an idea the theory led to, that happens to have been borne out via observation and evidence since then.
