I was reading an article about "Libyan desert glass" today, and how the scientists are totally perplexed on how it formed. It is primarily silicon, but it contains microscopic zircon crystals - and it has been fused at temperatures unlike anything ever found on Earth - even in molten magma.
The general opinion is that it formed in a meteorite burst over Libya in antiquity - but the scientists still say that doesn't fully explain the intricate atomic patterns found inside the glass.
More recent scientific studies say the Libyan desert glass was formed via a massive asteroid impact. But the problem with that line of investigation is - there is no impact crater anywhere near the Libyan desert, capable of supporting that story. The experts claim the crater is depply buried under the desert sands and needs more investigative work to find it.
In the article, they showed the Winged Scarab Pendant found in King Tut's tomb. It contains Libyan Desert Glass amongst the inlaid gemstones. Now, just looking at the close up of the pendant, I'm blown away by the skills, the complexity and the workmanship in this pendant. The experts say the ancient Egyptians were a race of primitive idol-worshippers who somehow managed some impressive building feats such as the Pyramids, using primitive transport methods.
They had no electricity, no high-tech steels, only wood-fired furnaces, no modern grinding equipment, and supposedly just primitive hand tools. I call BS on those suppositions - these people were an advanced race with skills and equipment equalling modern techniques.
It takes over 1000°C to melt gold, and intricate, high-tech tools to work it - to cut gemstones - and it takes artisans of exceptional skill to cut and shape those stones and fabricate the precious metals into shape. Take a close look at this pendant, you can expand the photo substantially to see the detail.
