It is my belief that during the latter stages of ‘recent’ chaos there was a two, or possibly three way planetary encounter with Mars above the Himalayas (dragging them up), the Moon above the Sinai desert (the moon god SIN raising a few mountains) with Venus above, and dragging up the Andes.
With globe in hand, you will note the antipodal point to the ‘docking scar’ of the Himalayan complex is just off the South American coast – flanking the Andes.
El Niño caused by sub-surface tidal heating, the legacy of a time when Venus danced with earth.
