I found this pdf about the Lybian Desert Glass (LDG) by Christian Koeberl.
Where it was found, he analizes the chemical composition,
comparisons with rocks, source etc...
But anyway, I found it very interesting to just have an objective list of chemical
composition of LDG.
He states the glass has "unambiguous cosmic components". OK, we can agree
with that, I guess.
But he concludes it MUST be a product of a huge explosion after an extraterrestial
rock hit the earth and glass was formed by high temeprature and pressure.
So here is his "highly scientific proof": "It is clearly from an impact even though the
source crater has not been found." hahaha. Enjoy!!!

According to some experts tha lbyan desert glass (interestingly can be found in entire sahara but called libyan - recommend to google 'ancient ruins/sites Libya & 'kinetic war Libya') - there was a huge nuclear kind of explosion which happened thousands of years ago, which made the sand become this special green glass. Not an expert on anything - though my father was a physicists genious who was put on a shelf not to reveal 'things' - but what I think is that when that explosion happened the interaction among the different elements exsisting within the 'dome' or inside the 'ball' aka glass ceiling & the desert sand created this green glass or what Steven's opinion is, it just felt down. Just guessing.
I used to ascribe to the nuclear desert glass theory but when I realized exponential nuclear fission reactions are not actually possible I no longer believe in ancient aliens possessing such weaponry either. This of course doesn't mean they did not have huge weapons of mass destruction.
