His stock in trade is to confirm biblical events and here his agenda is to confirm the Noachian flood so as to confirm the real world validity of his Xian dogma. I don't see him off looking for Utnapishtim's boat up Mount Nimush, which let's face it is where we get Noah from, no, he's trying to make the Bible real. This is not science, it's work back-ways by deciding the end result a priori and then looking for any evidence to confirm those assumptions until it's found.
As for his books, only the latter is a wish fulfillment armageddon fiction; which itself indicates a holding of rather fundamental evangelistic views. The former,The United States in Biblical Prophecy
is not a fictional work and is an allegedly historical work described thusly on Amazon, "This manuscript examines former claims about the United States in biblical prophecy, evaluates newly identified passages that correlate with this polity, and attempts to discover the destiny of the American nation." So they have form for making their chosen superstition the object of their work thus compromising their objectivity.
Higgs boson, dark matter, dark energy, black holes ...
I'm sorry but there is no correlation here, the above are objects posited to exist by a particular scientific theory, developed through reason. Thus if the theory is at least somewhat correct we should expect to find these objects and so confirm or deny the theory's validity or current structure. These theories generally have other components that have been confirmed and so at least have some footing, black holes have been confirmed, dark matter inferred to a degree and the rest, the research goes on. If the Higgs and such are not found then the theory will be reworked or if falsified completely, it will be discarded; such is how science works.
The ark and its ilk were not arrived at by scientific research, they're the product of bronze age goat herders in the Middle East region who were amalgamating another groups made up tales of yore. Tales to explain events and a world they lacked the tools to properly understand, tales we now know to be largely mythical works of allegory and often with a long history of remaking down the ages to suit new societies. At some later stage some other folks decided to make this evidence-less global flood event part of their dogma, thus declaring that it had happened and had done so because the sky tyrant desired it and not merely allegorical tales. Believers, later still, encountered a problem. Allegedly real events should have evidence, however, there is none. Instead of understanding allegory they wander off to confirm whatever fantasy they wish were true and no amount of failure falsifies their notions; at best they will merely retreat to faith. Because it is not merely a theory or hypotheses which is wrong, their entire world view is at stake. If it is conclusively falsified then that means they are no longer special, no longer the centre of the verse, no longer among the saved, no longer destined for eternal reward and all that time spent adhering to pointless rules wasted; that provides significant impetus for bias.
The cart is very much before the horse, something for which they have no good reason to believe exists, something which was not arrived at through reason but merely because it is an old story and some punter long ago randomly decided it was real, and something with a clear history of genesis in older societies tales; it's an exercise by a fervent believer to have more than the faith they deep down know is not good enough. There is not the slightest similarity between that and how scientific hypotheses are developed or researched, otherwise the contradictions alone in that book of bronze age tales would have clearly marked it as the product of humans and not an historical record, or word of some god. Correct analyses would show that, which is why they don't do it.
Hope is but the first step upon the road to disappointment.
