Imagine that.
Intelligent (presumably) scientists develop (design) an experiment that sheds no new light on how they think that life on earth might have begun because it's all based on unsubstantiated presumption.
If these people could just step back from their philosophical revulsion regarding tradition and morality long enough, they might realize that it’s far more plausible that life was placed here by some external agency, than clinging to all the millions and billions of years they require for life to have somehow self organized and mindlessly improved itself.
Just when did the notion that genuine “science” absolutely cannot allow for outside intervention in the origins of life on Earth arise? I’m guessing the 30’s. Hubble was well along with advocating the denial of any conclusion that led to an assumption of exceptionalism for Earth or even this solar system by 1937.
