Giant Squids — Not Just Legends

Release the Kraken! Anyone for calamari? Well, you can have my portion. However, when it comes to the giant squid, I guess they're not good eats, so stay with the smaller varieties for that . Let the sperm whales dine on them. Giant squids have been elusive (partly because of where they live, deep in the ocean, for which they are well designed) and considered the stuff of fanciful legends because of evolutionary presuppositions. Except for the unlikeliness of them attacking ships at sea, recurring legends like this often have a basis in fact. Creatures did grow larger long ago, and we have not explored all that much of the ocean, really, so it should not be such a surprise that giant squids have been found. What else is down there, I wonder? Tales abound around the world of the existence of awesome creatures and events. For instance, the hundreds of stories of a global Flood, with amazing parallels to the original in Genesis, give strong support to the truth of the Bible’s re

Rapid Reef Growth? We Don't Mind Atoll

One of the criticisms of the biblical timeline is the growth rate of coral reefs and atolls. Using uniformitarian assumptions which include that growth rates today are the same as growth rates in the past, calculations supposedly prove that the Bible is wrong. However, as we have seen numerous times, "the present is the key to the past" plus other assumptions backfire. Coral Reef, Virgin Islands — USFWS / Gary M. Stolz / PD Reefs grow more slowly than coral. Reefs have varying growth rates, and can be very rapid. Complicating factors are found in the Eniwetok Reef in the Marshall Islands. This thick reef is not entirely reef, because about a mile of it is limestone resting on an underwater volcano. But still, questions arise as to how the entire package can appear the way it does in relation to Flood models. Creation scientists have proposed models based on theories and observations that offer a very plausible explanation. Modern ocean reefs can be quite massi

Sediments, Bioturbation and Uniformitarianism

Here is another example of uniformitarian presuppositions being proven wrong, this time in the deep blue sea. The bioturbation of sediments by trace makers is often perceived by naturalists as a process requiring extensive periods of time. Little experimental work has been conducted to either support or refute such a concept. However, recent laboratory analysis indicates that the bioturbation of marine sediments can occur within short periods of time. Bioturbation experiments Marine worms, bivalves (clams), arthropods (shrimp and crabs), and echinoderms (sea urchins and brittle stars) are just some of the many animals that live on or in marine sediments (figures 1 and 2). The study of traces created in sediment is identified as ichnology (Gk ichnos = trace).  Recently, an investigation was conducted to determine the rate that select bivalves, arthropods, and echinoderms could bioturbate marine sediments. The animals were collected from
