In case it wasn’t obvious, I’m completely for exploring the universe as best we can from our vantage point in an ordinary corner of an ordinary galaxy, in what will probably turn out to be an ordinary solar system, even when there are no immediately obvious practical benefits.
What I’m strongly against is the serious discussion of massively unlikely (however entertaining) explanations for perfectly explainable phenomena like remarkably precise ancient stonework, massive artworks, large ancient structures, and the like. (But I have nothing against those fanciful explanations being used as fodder for fiction.)
