This video responds to a video by YouTube user Thunderf00t, entitled "Why do people laugh at Creationists? (part 29)"
In my video, I explain a few of the fundamental flaws in the argument that Thunderf00t uses. Thunderf00t argues that piranhas are vicious killing machines, but they do not (generally) attack each other. Thunderf00t asserts that piranhas do not believe in God, but they do not do whatever they want to do.
I observe that Thunderf00t is unable to enter the psyche of fish to determine whether (in fact) they believe in God. I also note that Thunderf00t is unable to enter the psyche of fish to determine whether (in fact) they do not do whatever they want to do. In short, I note that Thunderf00t's entire set of premises relative to his argument are based on his own untestable assumptions regarding the psyche of fish.
From there, we turn to an investigation of his attempted application to human beings. We note that he claims that the same purely naturalistic mechanism that gives fish a code of morality also gives human beings a morality.
However, we note that we can get inside the human psyche and discover that, in general, human beings do believe in a divine law-giver and do intuitively understand that principles of right and wrong imply absolute and transcendent standards of right and wrong. Thus, if fish operate as humans do, we would expect to find that they too believe in God, in divine morality, and so forth. In short, Thunderf00t's hypothesis of sameness between fish and humans actually undermines his argument.
Finally, we conclude that Thunderf00t's argument is just another irrational attempt to deny that the moral law, written in the consciences even of atheists, comes from the moral law giver. While Thunderf00t attempts to go ad hominem on Ravi Zacharias, he has no cogent argument for morality being produced through purely natural mechanisms.
