Building block of life found on comet leads to more comet panspermia from the neo-scientists.
The amino acid glycine, a fundamental building block of proteins, has been found in a comet for the first time, bolstering the theory that raw ingredients of life arrived on Earth from outer space, scientists said on Monday.
[Presupposition 1: Life did not originate on earth; ‘raw ingredients of life arrived on Earth from outer space’ say the neo-scientists.]
Microscopic traces of glycine were discovered in a sample of particles retrieved from the tail of comet Wild 2 by the NASA spacecraft Stardust deep in the solar system some 242 million miles from Earth, in January 2004.
Samples of gas and dust collected on a small dish lined with a super-fluffy material called aerogel were returned to Earth two years later in a canister that detached from the spacecraft and landed by parachute in the Utah desert.
[Good data on collection of sample; no presuppositions here.]
Comets like Wild 2, named for astronomer Paul Wild, are believed to contain well-preserved grains of material dating from the dawn of the solar system billions of years ago, and thus clues to the formation of the sun and planets.
[Here we go again. Presupposition 2: comets date from the dawn of the solar system billions of years ago, and they contain well preserved materials. What? This is more preposterous than the well preserved 65 million year old dinosaur tissues and blood cells. And these folks think they have a clue about the formation of the sun and planets?]
The initial detection of glycine, the most common of 20 amino acids in proteins on Earth, was reported last year, but it took time for scientists to confirm that the compound in question was extraterrestrial in origin.
[Presupposition 1 affirmed; the glycine is ‘extraterrestrial in origin’. But how did they determine that?]
"We couldn't be sure it wasn't from the manufacturing or the handling of the spacecraft," said…the principal author of the latest research.
She presented the findings, accepted for publication in the journal Meteoritics and Planetary Science, to a meeting of the American Chemical Society in Washington, D.C., this week.
[If this stuff is peer reviewed, then what does that say about the peers? They must all be neo-scientists. The important claim of ‘extraterrestrial in origin’ is not addressed here. Extraterrestrial fits better with their theory, therefore it must be right.]
"We've seen amino acids in meteorites before, but this is the first time it's been detected in a comet," she said.
Chains of amino acids are strung together to form protein molecules in everything from hair to the enzymes that regulate chemical reactions inside living organisms. But scientists have long puzzled over whether these complex organic compounds originated on Earth or in space.
[The neo-scientists ‘have long puzzled over whether these complex organic compounds originated on Earth or in space’. They are puzzled because amino acids do not occur naturally but are associated with living things. DNA occurs naturally too, around living things. The neo-scientists have taken on a big problem in trying to refute bio-genesis, but they are well funded and working hard on a solution.]
The latest findings add credence to the notion that extraterrestrial objects such as meteorites and comets may have seeded ancient Earth, and other planets, with the raw materials of life that formed elsewhere in the cosmos.
[There it is: There is nothing special or unique about earth; life was seeded here with raw materials of life that formed elsewhere in the cosmos. How does this thinking help the neo-scientist with his theory? They still have no explanation for the origin of life elsewhere in the cosmos. The Biblical revelation is essential for man to know his origin. When it is suppressed the best that autonomous man can devise is panspermia and macro-evolution.]
"The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare," said…the director of the NASA Astrobiology Institute in California, which co-funded the research.
[Another leap of faith: glycine in comets implies amino acids are prevalent in space and therefore life is common. Comets are associated with the solar system; they orbit the sun. So why are we looking for life outside the solar system, if comets are the bearers of life? Shouldn’t they be asking how glycine happened to be riding on a comet? Why not consider that comets originated from earth? Welcome to neo-science where irrational presuppositions from an irrational theory leads to irrational group thinking.]
Thanks to Steve Gorman for some comic relief.
