We agree with them that glass could be formed a lot of different ways. We don’t have a problem with that,” said Allen West, a retired oil and gas executive who is one of the leading proponents of the theory.
“You can get them from grass fires but you also get melt glass from lightning, volcanic eruptions and you also get it from cosmic impacts. The trick is being able to tell them apart.”
West said house fires don’t explain why they found evidence of particles from the Syrian soil and in North America that contained rare minerals like suessite, which melts at 4,100 degrees, and corundum, which melts at 3,200 degrees.
“No building fire can create those temperatures, a fact that refutes their hypothesis that this glass was produced in low-temperature building fires,” he said. “The sad thing is that these guys ignored all the high temperature evidence.”
So it’s clear the debate will go on.
West said he and several other supporters of the impact theory are readying papers that will provide further evidence of additional cosmic minerals at the sites, as well as more evidence shoring up the dates of the impact sites.
“The only time these melted minerals are seen in glass is when there was a cosmic impact or an atomic bomb blast,” West said of the new findings. “We can pretty much rule out an atomic bomb in Syria at that time.”
