Astronomers Find Oldest Known Asteroids 72
Researchers from the University of Maryland have recently discovered three asteroids that appear to be roughly 4.55 billion years old, dating back to the formation of the Solar System. The scientists say that the asteroids have survived relatively unchanged since that time, and make good candidates for future space missions.
"'The fall of the Allende meteorite in 1969 initiated a revolution in the study of the early Solar System,' said Tim McCoy, curator of the national meteorite collection at the Smithsonian's National Museum of Natural History. 'I find it amazing that it took us nearly 40 years to collect spectra of these [CAI-rich] objects and that those spectra would now initiate another revolution, pointing us to the asteroids that record this earliest stage in the history of our Solar System.'"

But your point about the "gods of research" is disingenuous... that is unless you believe that one is better off putting their faith in intelligent designers and corporate-science-sophistry. It's true that science could be *more* conservative with declaring findings, but really it's a question of who is more credible with the facts, and more pliable when it comes to standing corrected.

This is not a negative connotation, this is the whole point. If someone refuses to revise their opinion regardless of new data (whether the data is for or against or not), that is faith imo. It is also the antithesis of the scientific method.
The upshot is, to the open minded, science and spirituality are not mutually exclusive until such a time that we can observe _everything_, in which case there would be no more mysteries anyways and life would be quite boring.

this sort of impossibility twaddle is easily discredited. For example, tall buildings or arched/suspended bridges could not be erected without a scaffold or crane. But once erected those are removed. Just because there is no evidence to be found that they were there does not mean the buildings sprung into existence fully formed.

Recently Behe's claim that the flagella motor protein could not have evolved because it's inoperable without one of it's many parts and thus has no function was shown to be wrong. SPikes used by some bacteria to penetrate others turn out to be almost identical to the motor protein assembly but with a few proteins removed. it's not a motor it's a syringe.
Bombadier beetle.
Oxidative enzymes and fizzy action are good ways to digest something in your mouth cavity. It would be no surprise if the bombadier's enzymes were developed for digestion and then later recruited for defense. Many animals regurgitate or spray digestive juices as defensive or offensive weapons. Even single celled organisms secrete highly indesructable proteases to destroy the competition. Others, like the Spike bearing ones have cannons they can shoot this from. If single celled organisms can evolve this its not a stretch to imagine a beetle pulling it off.
Giraffe.
Many animals, like diving douplhins, seals, whales pull off similar stunts at orders of magnitude greater pressure differentials. Thus not only had such mechanisms evolved while we were all sea-bred creatures, and vestigal mechanisms potentialially latent in our DNA, but the specific machanism in Giraffes is not the only way to skin the pressure cat. For example, airplane pilots who work at High-Gs know that clenching muscles can prevent vaso-dialiation consequently fainting. It's not hard to imagine that early long necked creatures could survive without this adaptation, and the means to re-evolve it was possible in DNA
Woodpeckers:
this one can be dismissed. There are lots of birds that eat tree bugs by whatever means they can dig them out. trees come in all denisities. You don't need to evolve to be a wood pecker in one go.
Rapid Canyon formation.
I happen to live on the base of a caldera. My house is perched 200 feet over a straight drop to the steep walled canyon bottom. This was carved by a combination of massive floods and slow erosion. Simmilar examples abound around the area. But the origin of the massive floods is well known too. The caldera would periodically block it's outflows and then fill with water. when these dams burst torential fllods would scour the soft volcanic ash and aleufial sands into canons that would harden to rock. Similar stories can be said about the hells canyon area.
I've seen it happen in a small way in my own life time when forest fires glazed the mountain soils turning run-off trickles into 40 mile per hour flash floods digging 10 foot channels.
You really need to not assume the first silliness someone pours in your brain is the truth.

You miss the point (as you did many times in your post since I started from the bottom and worked my way up). Your analogy is incorrect. The "scaffolding" is still present in the animals I provided as examples. The "scaffolding" is also still needed and was always needed for the animal to survive. Your burden of proof involves showing these animals could survive without any one or more of the features I noted. If all those capabilities are required at once we have a problem.

There are many examples of animals which could not have developed gradually through evolution without dying off because without all their current physical properties the animals would not survive for evolution to try again.

Can your view point explain why human beings hiccup? I'd really, really like to see your answer on that one...
In case you were wondering, the reason why we hiccup is because we descend from creatures of the sea! In case you're skeptical, I went and found a write up from "New Scientist" (A fairly credible layman's scientific source).

Depending on the speed of each of these factors you get different scenarios. Rings could never happen, they could disappear before the sun is created, they could be be created before , during or after planet creation. Planet creation could also start before the sun. You get the idea.
