"I wonder, what existence designed this whole thing?"
"There are many people who say there's a God somewhere up there, but God is nothing more than a formula. Just a part of some law of physics that we have yet to understand."
Evolution prevails! :D
I don't think that it's anywhere nearly that simple. It seems to me that the concept of God isn't anywhere nearly so easily dismissed from a teleological standpoint as Dung Beetle makes it seem in that passage, and it seems to me that he realizes that fact. His expression moves from blank reception to a sort of nihilistic smile and then to a sort of grim determination as the conversation moves from page ten to page seventeen.
I think that it's far more probable that Kitoh is using this offhand declaration to reveal another aspect of the human vulnerability than as any sort of logical endpoint. Dung Beetle's character seems to be one that cannot logically progress without first rationalizing his actions, and added to the sum of his effortless and sarcastic behavior throughout the entirely series, it seems inevitable that he turns that some form of hedonism in order to maintain his sanity. The statement seems to be satirical of the many who offhandedly declare only consensus reality by way of either the scientific method or some sort of philosophical deduction, as it is distinctly clear from the series that either in application to the situation at hand fails miserably.
Further supporting this is the continuation of his argument; "It's better to think like this, no?"
Given that he appears to be talking with the Kokopelli at the start of the series and his separate approach to the new world, telling the children directly that they would die, he seems to assume the viewpoint that it is far better to make progress through sacrifice in full knowledge than with only hope in ignorance. He certainly does not know the answer to the whole riddle, since it looks to be impossible to know more than the cursory details from but he thinks that coming to the best conclusion that he can and believing in his deduction is the proper course of action.
Another point that seems to support this is that he is able to treat this so flippantly after seeing Jun, the most reluctant and in many senses most rational of the pilots, sacrifice much of his sanity massacring multiple civilizations.
Your comment was probably a joke considering how clear most of these points are, but a part of me just couldn't resist responding to this and couldn't muster the control to let it go by. :P.
