The first supernova was probably about 450 million years after the big bang, when the first, massive stars (Population III stars) exploded filling the Universe with the first heavy elements.
These elements were "absorbed" by population II stars, which again exploded as supernovae. These metal enriched stars populated the Universe with the rest of the known elements.
So supernova were around well before life on Earth. In fact without supernovae there would be NO life on Earth.
