The Barberton Greenstone Belt in South Africa is estimated at 3.4-3.6 billion years old, and generally regarded as the world's oldest mountains.

Mount Everest isnât actually the tallest mountain â Ecuadorâs Chimborazo beats it. All of those that have bravely climbed Mount Everest might have done so in vain â they werenât climbing the worldâs highest mountain after all, according to scientists. The Himalayan mountain is actually beaten by Chimborazo, in Ecuador. But Everest still wins on the traditional metrics: itâs nearly 9,000m above sea level, thousands more than any of its closest rivals.
