Time Travel
montana i think you're making similar shortened leaps like the blogger. their argument may be more fantastical but your explanation is every bit as subjective. the IDBs clearly travel through a human future, collecting artifacts first then land in the far past and build their temple. again: their vehicle is surrounded by artifacts buried in the far past collected from the future. clearly they don't travel through space-time again until the skull is returned, a simple detail you're overlooking. and i think you might want to look into Quatermass and the Pit, which has and equal share of the sourcing of KOTCS
