I would expunge the word "aptitude" from our vocabulary, because if you're interested in something, that's all that matters.

We still don't know for sure what the trigger was, but since we've discovered meteorites with supernova dust, we do know that a violent explosion rocked our cosmic neighborhood at the time of our birth, and it's quite possible that without it, our stable, stately solar system would never exist at all.
