A gigantic meteorite impact 800,000 years ago threw this impact melted rock into space where it rained back to Earth as Tektites. These Tektites were collected by my uncle in Australia deserts some 30 years ago.

Fascinating objects, which are the result of a giant meteorite impact. The Australasian strewnfield, covering at least one-tenth of the Earth’s surface, is the largest and the youngest of the tektite strewnfields. The 800,000 year-old strewnfield includes most of Southeast Asia and reaches far out into the Indian Ocean and south to the western side of Australia. The impact crater may have been between 32 and 114 kilometres in diameter.
The terrestrial-impact theory states that a meteorite impact melts material from the Earth’s surface and catapults it up to several hundred kilometers away from the impact site, which means that it must have travelled through space. The molten material cools and solidifies to glass. This explaining the dryness – tektites are among the “driest” rocks, with an average water content of 0.005%.
