When I went to the Mammoth caves, the guide told us the rock we saw around us was madeof limestone. He explained limestone is made from the bones of sea creatures.
The term "bones" are not really representative of what is going on. A large amount of limestone is composed of the "shells" (called "tests", because they are not the same as the shells of shellfish) of a type of protozoan called "foraminifera" see

The shells and other calcareous detritus associated with reefs (not the coral reefs of today) is another source of limestone. See for an example in Kansas:

The third type of limestone is called "oolitic" and derives from pellets called oolites composed of inorganically as well as organically precipitated limestone:

Oolites are indicative of the wave action of shallow water.

Do you feel that "equalibrium" to be at work during a glabal flood that lasted for months?
Basically most of the geologic record is totally inconsistent with the notion of a "worldwide flood lasting for months", which is why geologists don't believe in it.
As to Austin's claims about coal, these issues have been addressed (and disposed of) by geologist Robert Gastaldo in:
Gastaldo, R.A. 1999. Debates on Autochthonous and Allochthonous Origin of Coal: Empirical Science versus the Diluvialists. In Manger, W.L., ed., The Evolution-Creation Controversy II: Perspectives on Science, Religion, and Geological Education, The Paleontological Society Papers, v. 5, p. 135-167.
(ID propaganda movie "unlocking...")
It seems to me they gave some strong evidence for ID.
They were playing to people unfamiliar with the issues and methods of science. Real scientists are not impressed by the claims of creationists.

Chemical biology is science, and it's making it really hard for evo to get a start.
Evolution is the glue that holds all of biology together. As I have said before, it is not possible to disprove evolution (origin of species) with arguments about abiogenesis. These are two different subjects.
(Polarized UV light making left handed
chemistry)
So polarized UV light + essoteric soup = sequnced left handed amino acid chains?
(modern abiogenesis issues)
Mighta, coulda but... let's wait and see what they say next week.
(left handed chemistry is biochemistry)
Synthesizing what already works. Left handed amino acids don't just stick together unless it's in a living organism. We can't assume a living organism to give darwin a leg up, that's circular reasoning.
My point with all of this is that the creationist arguments all claim *categorically* that it is impossible for some aspect of abiogenesis or of biological evolution to have happened. Yet, when we examine the claims of creationists closely, we find that either the argument given is utterly false (such as your claims about lefthanded amino acids "not sticking together"), or that the creationist is harping about something that is not well understood by anybody. In short, the arguments of the creationist are either false, or are either arguments from ignorance.
"Howard Hughes Medical Institute (HHMI) researchers have discovered that clays may have been the catalysts that spurred the spontaneous assembly of fatty acids into the small sacs that ultimately evolved into the first living cells."
mighta...
Yes. There are encouraging laboratory experiments which indicate this as a possible mechanism. The clays act as catalysts in the lab. Something similar may have been going on in the early Earth's environment.
Actually I just read where a German scientists almost got two left handed amino acids to stick together, unfortunatly they didn't include what the "evironment" was like.
Reference? Basically, I believe you are misunderstanding the issue.
So, now we go from essoteric soup to essoteric sludge. I can't wait to see more research.
Neither can I. At least scientists *do* research. Creationists, do not do research.
The trouble is, there is no research yet describing how all the info to make a brain out of clay got in the RNA.
Sure there is. It is called "evolution". Once you get to the RNA stage, it is all descent with modification and natural selection. The rough sketch is known. It is filling in ever greater precision of details that is the science. No it is not cut and dried, but we do not live in the dark void of ignorance and superstition.
(Brains as electrochemical machines)
I'm sorry, but holding a child in my arms is way more than random fires of a synapse. What a hollow emotionless life evo offers.
I never said it was "random". But yes, your baby is a biochemical machine. In reality an animal.. Just like you.
But let's talk about your baby for a moment. Do you ever wonder why it is you bond to your baby? After all, it is all rather strange. You have this foriegn organism that grows within your body, is ejected painfully, and then demands to be taken care of for decades.
As a baby, it basically is an excrement making machine, made of soft flesh, which in another form, you would happily cook up and server for dinner. Do you ever wonder why you look at it as beautiful? You'd think a person was on drugs or something to see something that looks like a cross between a slug and a miniature sumo wrestler as beautiful. Indeed, there is some powerful biochemistry going on there.
But what else, not only does mother Ninevah look at baby Ninette as being cute and darling. Basically you show her other species babies and she will think those are "cute" too! Think about that kitten or that cute puppy, or the bear cub, or the lion cub. In fact, any mammalian baby evokes a similar reaction.
The same body form that makes your baby cute to you, makes their offspring cute to you as well. Never saw a cute spider, or a cute snake, or a cute lizard though---all corelations of "cuteness" boil down phylogeny. Within the notion of evolution, common descent and the common relatedness of species, it all makes sense.
I don't know of any cultures that ever condoned rape. But anway, you really had to be told raping a kid was wrong?
You should read the Bible some time. All that stuff about having children by your wife's handmaiden (i.e. slave). Somehow that wasn't adultery. Nothing was said by the handmaiden being a willing participant.
(pedophilia)
Even an abuser knows it's wrong. Why else would NAMBLA be having such a hard time getting it's message out?
Actually the "awarness" being "raised" is to the opposite effect. The move is already underway to remove "social stigma" over child rape.
Basically, those pervs in NAMBLA think it's sexy to have sex with a child.They think they are "loving" the kids. So no, they are into it. They know that society doesn't approve of it, but they certainly approve of and enjoy the practice, and don't think that it is wrong, which is what makes them dangerous.
