No, it can’t. The existence of a supreme being simply is not a scientific question. A supreme being stands outside of nature. Science is a naturalistic process and can only answer questions about what is inside nature. Beyond that it’s a matter of personal belief.
What if someone claims that there is a god that exists outside the confines of the material universe? This being is unknowable to us mortals, one can only have faith in his existence. A believer can also claim that the existence of the universe was the will of this being. These beliefs are all inherently untestable.
The new ad says: “You KNOW they’re all SCAMS,” and it’s signed “American Atheists — Telling the truth since 1963.” “They” are at least five of the major religious traditions, as is made clear by a set of symbols accompanying the poster. … First, the ad is simply making a preposterous claim that cannot possibly be backed up by factual evidence, which means that, technically, it is lying (but see below for another interpretation). Not a good virtue for self-righteous critical thinkers.
