First creation was the creation of the Noor of the Prophet Muhammad (SAWA) and his holy Progeny (AS). Jaabir ibn Abdillah, the well known companion said that: I asked the Prophet about the first thing which was created by Allah. He replied me: The first which was created is the Noor of your Prophet. Bihaarul Anwaar , V.15, P.24. The creation of the Prophet and his holy Progeny was long before the creation of Adam (AS).
The creation of the Noor does not mean creation of the body which comes later.
