> Animals are not alien, they're part of the design for our happiness.

I think you took the word "alien" from my comment about animals more a bit less metaphorically than it was intended. At any rate, this comment is just a sermon, not knowledge.

> The evidence for this statement is that no one can make a cogent argument against what I say here.

Nobody can make cogent argument against statements of fact rooted in faith. You've stated you already know the absolute truth of the matter while making claims that are inherently unfalsifiable. How does one argue against animals being "part of the design for our happiness?" It's not a statement rooted in fact, it's not falsifiable as it touches on mysticism. What is the cogent argument beyond the ample evidence of our shared evolutionary history, and the repeated and growing empirical evidence for our similarities vs. differences?
