the existence of a soil is unfalsifiable, so I wouldn't be able to prove or disprove my clain.
As is the existence of the great juju on top of the mountain or the existence of goglack the toenail king who lives under your bathroom sink. The unfalsifiable nature of a claim doesn't warrant it any extra consideration.
As someone who grew up in NSW it's 14 and 9 months. Exceptions might exist for family businesses etc. but your 8-year-old can't apply for a job at Woolies.
