Answers in Genesis gets email, and they recently published a critical message which they then thoroughly rebutted. Not.
Their critic pointed out the absurdity of believing the earth is only 6000 years old and that dinosaurs and humans lived together, and also made the point that an indifferent nature is not influenced by biblical beliefs. AiG answered, and it’s actually rather interesting as a condensed summary of their fallacies.
The first chunk is a table of ages, showing that scientists have steadily revised the estimated age of the earth upwards over the last century. It’s true; scientists are very open about how they arrive at their conclusions, and use the best techniques available to make their measurements. You can, for instance, browse the International Commission on Stratigraphy and see that the dates do regularly shift as new observations come on. In particular, there was a major change in the middle of the last century as the new techniques of radiometric data came into play; before that, estimates were made on the basis of planetary cooling rates (greatly flawed because they didn’t understand radioactive decay as a source of internal heat), and rates of sedimentation and erosion.
To AiG, this is a weakness.
An evolutionist could look at this chart and say, “See, scientists are continually studying the data and refining their answers, so we now have the age of the earth and dinosaurs narrowed down.” We agree that scientists should continually refine their views as new information becomes available, but that is precisely the problem when it comes to this topic. Evolutionary scientists have changed “common knowledge” multiple times over the past century, yet the Bible has not changed. It still clearly teaches that the universe, earth, and dinosaurs were made during a six-day period about 4,000 years before Christ.
What they call a “problem” is a strength. The earlier dates they cite were all developed by studying and publishing the evidence; the revised dates came about because other scientists examined the evidence and challenged it by acquiring more date and better tools.
Only a simple-minded fool would consider clinging to an old idea in the face of new evidence to be a virtue. Show me reasonable evidence that the current dates are wrong, and I’ll accept that. So that’s what AiG should do, right? Show us the evidence that the Earth is only 6,000 years old? Here it comes!
Furthermore, a great deal of evidence [Get ready to start counting their evidence!] exists that is perfectly consistent with the notion that dinosaurs and humans lived together. First and foremost, the  Bible states that man and all land animals were both created on Day Six. Since dinosaurs were primarily land animals, this means man and dinosaurs lived at the same time. Also,  Job was told to consider the behemoth (Job 40:15–24), a creature whose description seems to match that of a sauropod dinosaur. In addition to the biblical testimony, we have discovered  pictographs, petroglyphs, and brass carvings of dinosaurs,  soft tissue and red blood cells in a tyrannosaur femur, as well as records from cultures around the globe of  dinosaur-like creatures (often called dragons). There are even some reports that  some dinosaurs may still be alive, though we need to be careful to verify such reports.
So the  eyewitness testimony (God’s Word) tells us that earth is about 6,000 years old, and He is most certainly a reliable witness. In fact, it is  impossible for Him to lie (Titus 1:2; Hebrews 6:18). Also, the historical data is perfectly consistent with the idea that the earth is young and that dinosaurs and man have lived together.
In all that noise, I only saw three different arguments, at best.
Bible, bible, bible. Nope, sorry, ancient work of myth and fable ain’t objective evidence…and no, telling me that the Bible says it is infallible isn’t particularly persuasive.
People invent stories of monsters. That indigenous peoples everywhere have rich imaginations is not evidence that their nightmares existed, and hearsay can’t be used to demonstrate anything. Tolkien’s Ring trilogy is not evidence that elves existed, and Hollywood CGI does not demonstrate that aliens are visiting the planet.
Maybe this one ought to be crunched into #1. The Bible is just one specific example of a myth.
The T. rex soft tissue is from 70 million year old bones. Their age is not in dispute. Does this count as evidence for a young earth when they demonstrably do not understand the evidence?
And then it gets weird. When their correspondent suggests that they might actually learn some real science, for instance entomology, which shows the irrelevance of their book of magic and hatred, they say, “Nuh-uh, we don’t need to!”
I don’t need to leave the museum or take an entomology class to conclude that ants are indifferent about Christianity. Since ants are not made in the image of God and do not have the ability to reason, I do not expect them to care about Christianity; although, we can learn some lessons from them about hard work (Proverbs 6:6–8). Nor would I expect that dinosaurs worried about salvation from sin.
The entire universe shows a complete lack of concern about the narrow, ignorant beliefs of Christians; ant and dinosaurs are heedless of the need for salvation, because it is an entirely imaginary concept used by godly demagogues to keep their flocks in line. If the fools at AiG actually looked at the Book of the Universe rather than their cheesy incoherent Book of Lies, maybe they’d learn which is the greater.
