Do you think someone might have asked that question before?
According to Access to Insight, many of the suttas include the following quote,
At Savatthi. There the Blessed One said:
"From an inconstruable beginning comes transmigration. A beginning point is not evident, though beings hindered by ignorance and fettered by craving are transmigrating & wandering on.
In other words the "first" is not evident (or, I'd read that as, it's not evident that there is a first).
