No, it's just the old tactic of hyperskepticism to find some flaw. Standard courtroom lawyer tactics: try to make some doubt.
"As the universe expanded, according to current scientific understanding, matter collected into clouds that began to condense and rotate, forming the forerunners of galaxies. Within galaxies, including our own Milky Way galaxy, changes in pressure caused gas and dust to form distinct clouds. In some of these clouds, where there was sufficient mass and the right forces, gravitational attraction caused the cloud to collapse. If the mass of material in the cloud was sufficiently compressed, nuclear reactions began and a star was born."
Here is the pinnacle of our logical thinking scientists.
The universe expands, matter collect into clouds, the clouds mysteriously condense and rotate. Condensing I could accept but why would a cloud of matter want to rotate?
Here's the tactic at work. Ignore that this is a summary of several hundred or thousand scientific papers and is off the main topic if the pamphet -- which is biological evolution -- and demand details that the pamphlet doesn't have time for.
As it turns out, the current issue of Discover magazine has the details. The processes described arise from the physics that we know. It's the cover story in the December issue. Read it and get back to us.
"If the mass of material was sufficiently compressed" by what force did what get sufficiently compressed?
Gravity.
A little further down it reads
Experiments conducted under conditions intended to resemble those present on primitive Earth have resulted in the production of some of the chemical components of proteins, DNA, and RNA
This is written so vague it boggles the mind, and made me laugh out loud.
Go to the thread "Life from non-life: protocells" and read the details. Again, you have a small pamphlet and you laugh because it only gives you the basic summary?
Now they continue writing:
Some scientists favor the hypothesis that there was an early "RNA world," and they are testing models that lead from RNA to the synthesis of simple DNA and protein molecules.
Yet they forgot to mention that RNA does not just happen, thus whatever hypoidiotism they claim it lacks fundamental prove or a rational sequence of events.
RNA is made, on clay catalysts, from ribonucleic acids, which in turn are made from ribose, phosphate, and bases by simple chemical reactions. The bases and ribose, in turn, are made by even simpler chemical reactions when methane, ammonia, nitrogen, and oxygen are present.
Another tactic is selective quotes. For instance, the pamphlet does give a rational sequence of events: the building blocks were made by chemical reactions on earth or in space (and the chemicals landed by meteorite or comet), RNA forms from chemical reactions (perhaps catalyzed by clay), the RNAs are also enzymes (Henry "forgot" to mention that) and can make copies of themselves, the ribozymes undergo spontaneous changes and thus provide the basis of selection for autocatalytic activity, the RNA makes proteins and, later, DNA, the assemblages of RNA become packaged into protocells.
Now, below the place Henry stopped copying is the sentence: "For those who are studying the origin of life, the question is no longer whether life could have originated by chemical processes involving nonbiological components. The question instead has become which of many pathways migh have been followed to produce the first cells."
So true. I favor Fox's thermal proteins and protocells, but the RNA world holds promise and there is no reason it couldn't have been a combination of both.
Thanks, Henry, I had a good laugh reading your post and watching the humorous tactics of creationists (and slippery lawyers) once again. Norman Macbeth and Phillip Johnson would have been so proud.
