2 Mya proto-human intelligence started increasing extraordinarily quickly, coinciding with the appearance of stone tools and fire
Cp. Prometheus and the Watchers, which mythical memories attribute fire and advanced knowledge & metallurgy to other worldly powers intervening into human history to transmit those knowledges to humanity
The exceptional growth of human technology, from stone tools and fire 2Mya through to present day could be construed as evidence of heavenly intervention into human history and cultivation of humanity for tool use and technology
