Re:self replicating machines will inevitably evolvAnd that, in a nutshell, is why creationism can be believed by otherwise intelligent people. It is? Evolution is a numbers game. Evolution is slow, so slow that we can't really conceive of how slow that is. Slow? Is it now?

Evolution proceeds at different rates depending on the environment. If a population of long, medium and short tailed monkeys has all of the long tailed ones killed in a generation, then the species has evolved in that one generation... 5 years? The genes for long tails have gone.
Random mutations now... Well that depends on just how good the copying process is, but no matter how good it is, it isn't perfect. There's no such thing as perfection in the real world so errors are going to appear and accumulate in offspring. As to those probes. How does it take for a million self-replicating probes to become a trillion. Depends how many offspring each generation have on average, the time between generations and available resources.... And if mutated machines predate on one another... No reason to believe they wouldn't. -
Re:Global Warming/Cooling Same thing.Gotcha covered!
It doesn't matter. Global warming, global cooling - both at the same time! (e.g. google "global cooling")
As long as man is bad, all is good.

Re:Gojira
Here is an excerpt from a previous post of mine, maybe this will help:
For some examples of living transitional species, look at dogs and wolves (which can be interbred), modern agriculture, and a few species of squirrels( On different sides of the Grand Canyon you'll find nearly identical squirrels, the difference being that on the side of the canyon that is higher, it is colder and you see that over time they've developed traits suited more for the climate and eventually became an individual species. Also if you take certain species of squirrels from say Pennsylvania and mate them with that same species from Ohio, they can mate fine, but try to mate it with a squirrel of the same species from California and it will most likely fail or be extremely hard to get to work because this species is on the verge of speciation where they form into two separate species that can no longer breed together.)
Anyone who claims that there is no evidence of transistional fossils or species is just plain and simple repeating non-sense, but no matter how much you say, it isn't true. Here is the known cladogram for just dinosauria, look at all transitions, and these are just the ones that have been found and proven, there are still large parts of the earth left to search, not to mention under the thousands of miles of ice at the poles which are currently unreachable but in the age of the dinosaurs were most liklely prolific with life. You kind find similar diagrams for *every* single species. When combined, it is huge, one of the biggest and best documented diagrams in all of man's history.
Hereis a very truncated version of the cladogram for modern killer whales, the full cladogram contains significantly more detail. The things I present here are just the beginning, actually look at the science in depth and realize what a well founded and proven theory evolution is.
The "Godzilla" croc doesn't go against evolution. Read this for one example of convergent evolution, which is what happened with this croc (having fish like and carnivorous features due to the niche it lived in). I have a feeling that certain aspects of the findings are being sensationalized by the media for headlines, i.e. the "Godzilla" nickname implies certain things about the croc that just aren't true, and the media is paying too much attention to the nickname. The species btw did not appear out of nowhere :) It was similar enough to previous species that it already was in a Kingdom, Phylum, Class, Order, Family, and Sub-Family. It only was given a genus and species, implying that it has more similarities than differences with already found fossils. Keep in mind though that paleontology is under 200 years old, so there still is alot to be uncovered... finding a brand new never before seen animal isn't that far fetched, further research and explanation usually fills in the holes if there are any.

Re:Not that hugeYeah, lots of people here are picking up on the overuse of breathless superlatives with this thing. It's kind of ridiculous. Four meters is hardly "huge" even by the standards of modern crocs, much less some of the prehistoric ones. (It does sound rather large for the sort of specialized marine crocodiles this beast was related to.) Quotes like "the most fearsome predator in the sea" (from the Science Daily article) are also silly, considering that this time frame was also the era of the giant pliosaurs, which could easily reach ten meters in length with jaws two meters long.
Still, I wouldn't like to swim in waters inhabited by these brutes.

Re:What ID is actually about
Organisms decompose very quickly.Regardless, there are literally hundreds of thousands of transitional species and fossils. Study the damn science before you assert dumb ass claims that were made by your local lunatic religious person.

Re:Obligatory Dilbert joke
...I can't wait to know if we're going to melt down, or alternatively, have an ice age...
Let's do both!
Don't laugh...it could happen... -
Re:Palm Treesmost of the plate movement is predomanently east/west due to north/south plate faults.
Which doesn't imply it was that way in the past. This link shows North America lying on its side on the equator 510 million years ago (earlier than palm trees).

Just display it in a nice case.

"Millions of years" MyopiaYeah, they're so smart they didn't even see evidence of a young earth smacking them in the face.
Miraculously, the blobs were the tracks left by the water scorpion, perfectly preserved as fossilised rock despite the passing of millions of years and the huge re-arrangement of Earth's surface involving massive geological forces like volcanoes and earthquakes.
Noooooo, perfectly preserved because they were made only a few thousand years ago. Perfectly preserved because powerful currents from a giant flood of biblical proportions dumped a pile of sediment on them before they could lose their shape. The process of fossilization occurs rapidly and has been observed both in the laboratory and in nature. (The motto of the linked site is: Your window into the Mesozoic. Can you see the incredible, widespread myopia of our culture?) It begins within months and is usually complete in a number of years (usually less then ten) depending on the environment. This is widely known and documented fact, not theory.
More breathless myopic statements:
Article by Jame E. Francis. "Arctic Eden," Natural History, January 1991, p.57 and 60:
"The remains of lush forests near the North Pole give a glimpse of the Arctic's subtropical past....Despite the passage of 45 million years, the wood retains its original color and is still flexible and burns easily. I quickly discovered that my geologic hammer was useless for collecting samples of the fossil wood; the next season I came better prepared with wood saws."
How do you think a magnolia leaf would change as the result of having been buried for 17-20 million years? Consider this remark from Nature, V.344, April 12, 1990, p. 587:
"When rocks containing these fossils are cleaved open, the freshly exposed leaf tissues are often bright green or 'deep autumnal' in colour, though they rapidly curl away from the substrate as they oxidize and dry out."
The author says that it was even possible to isolate the DNA of the leaves:
"But even the most optimistic estimate of the longevity of this molecule would not have predicted that fragments of substantial length would survive after tens of millions of years at the bottom of an ancient lake." (p. 587)
The Discovery Channel needs to have the same disclaimer that Miss Cleo has. For entertainment purposes only.
