What was gold used for in ancient times?
Gold was generally used for a couple thousand years solely to create things such as jewelry and idols for worship. This was until around 1500 BC when the ancient empire of Egypt, which benefited greatly from its gold-bearing region, Nubia, made gold the first official medium of exchange for international trade.
Why was gold valuable?
The metal is abundant enough to create coins but rare enough so that not everyone can produce them. Gold doesn’t corrode, providing a sustainable store of value, and humans are physically and emotionally drawn to it. Societies and economies have placed value on gold, thus perpetuating its worth.
Why was gold important in ancient Egypt?
Gold was commonly used to make jewelry and ornaments for two main reasons: the Egyptians believed gold to be the flesh of the sun god Ra and because gold was plentiful in the region. Artisans made amulets, death masks, diadems, ornamental weapons, vessels, and funeral art out of gold to adorn the tombs of pharaohs.

What would happen if we ran out of gold?
In real terms, it’ll probably take more than 20 years to deplete known reserves. As gold prices go up (which they inevitably will), recycling rates are likely to increase. On the other hand, as gold prices go up, rates of mine development and expansion will likely go up too. So they may well cancel each other out….
When and why did gold become valuable?
In fact, gold, between 1600-1200 BC or the Late Bronze Age, was becoming the basis of value for many valuable objects now being traded between Central Asia and the Mediterranean, including metals such as tin and copper.

Can Kepler 22b support life?
Such planets have the right distance from their star to support water, plus a suitable temperature and atmosphere to support life. “We have now got good planet confirmation with Kepler-22b,” said Bill Borucki, Kepler principal investigator at NASA Ames Research Center.
What planet is similar to Earth?
