I guess you didn't bother reading the link.....the reason there is no evidence is because like the link stated it would vanish after 200,000 years.

says who? you might believe that evolution is just a matter of trial and error, but if less complex systems tend to favor certain configurations (think crystals, think alloys, graphite and diamond) why categorically exlude the possibility that life has its favorites, too?

history is riddled with people who believed they knew it all, only to be invalidated once they died and were therefore no longer able to control research.

did you know that biology textbooks once contained beautiful illustrations of little men sitting in the heads of sperm cells

if green, fused glass is produced by natural processes how come we don't see them in action? meteor impacts tend to eject matter, so they really cannot cover large areas with pure (95+%Sio2) glass, can they? saying it was a tunguska type event is fallacious, because tunguska itself is disputed, for the simple reason that it's a post-hoc explanation, without known precedent and without confirmation.

Libyan Desert Glass is a natural glass composed of nearly pure silica (98 wt %). The formation of this glass, because of its unusual composition has for long been considered as mysterious. Chemical analyses show that the glass is locally enriched in meteoritic elements, with typical chondritic proportions. The only explanation for these observations is that Libyan Desert Glass results from a meteorite impact on a silica-rich target.

For a quick glimpse at what unsung surprises may lie in the Vedas, let us consider these renditions from the Yajur-veda and Atharva-veda, for instance.
" O disciple, a student in the science of government, sail in oceans in steamers, fly in the air in airplanes, know God the creator through the Vedas, control thy breath through yoga, through astronomy know the functions of day and night, know all the Vedas, Rig, Yajur, Sama and Atharva, by means of their constituent parts.

" Through astronomy, geography, and geology, go thou to all the different countries of the world under the sun." (Yajur-veda 6.21).

"O royal skilled engineer, construct sea-boats, propelled on water by our experts, and airplanes, moving and flying upward, after the clouds that reside in the mid-region, that fly as the boats move on the sea, that fly high over and below the watery clouds. Be thou, thereby, prosperous in this world created by the Omnipresent God, and flier in both air and lightning." (Yajur-veda 10.19).

" The atomic energy fissions the ninety-nine elements, covering its path by the bombardments of neutrons without let or hindrance. Desirous of stalking the head, ie. The chief part of the swift power, hidden in the mass of molecular adjustments of the elements, this atomic energy approaches it in the very act of fissioning it by the above-noted bombardment. Herein, verily the scientists know the similar hidden striking force of the rays of the sun working in the orbit of the moon."
(Atharva-veda 20.41.1-3).

civilisation is not a crystal or an alloy
you're making a straw man argument so that you can demolish it

Max Planck died 60 years ago and things have since moved on

yes at the start of the 18th century
is all your information this up to date ?

Only a few years ago, the Chinese discovered some Sanskrit documents in Lhasa, Tibet and sent them to the University of Chandrigarh, India, to be translated. Dr. Ruth Reyna of the University said recently that the documents contain directions for building interstellar spaceships!

Their method of propulsion, she said, was "anti- gravitational" and was based upon a system analogous to that of "laghima," the unknown power of the ego existing in man's physiological makeup, "a centrifugal force strong enough to counteract all gravitational pull."

Dr. Reyna said that on board these machines, which were called "Astras" by the text, the ancient Indians could have sent a detachment of men onto any planet, according to the document, which is thought to be thousands of years old.

The manuscripts were also said to reveal the secret of "antima"; "the cap of invisibility" and "garima"; "how to become as heavy as a mountain of lead."Naturally, Indian scientists did not take the texts very seriously, but then became more positive about the value of them when the Chinese announced that they were including certain parts of the data for study in their spaceprogram!

This was one of the first instances of a government admitting to be researching anti-gravity. The manuscripts did not say definitely that interplanetary travel was evermade but did mention, of all things, a planned trip to the Moon, though it is not clear whether this trip was actually carried out.
