Atheism and the existence of peanut butter

[Anomalocaris]

no, precisely like evidence in every scientific quest that required major reassessment of what direction the preponderance of evidence pointed to as new discoveries are made, but not at all like evidence for god.  

So called evidence for god may have at one time had a role indistinguishable, in the case of some uninformed people, from that of real evidence in a thoughtful pursuit of truth.   but for ever more they are not.  they are merely ruses to defend an ultimate position from which there can be no retreat, regardless of what better analysis of existing evidence, or shifting of weight of total evidence from new discoveries, might say.   so such “evidence” do not lay any path or point the way towards the truth.   rather they are random rotten timbers picked off the ground to make into barricade of aged timber haphazardly set in place where there is room around a nihilistic last stand.  

evidence of luminiferous ether, on the other hand, is genuinely evidence pointing towards a medium.  But the difference is the existence of the medium is not by any means an ultimate position.  there in fact is no ultimate position.   there is only the next position that evidence points to.   Up until michaelson Morley experient, preponderance of available evidence pointed to the medium.   michaelson morley provided extremely weighty new evidence that dramatically shifted the center of gravity of the total body of evidence.   so preponderance if evident now pointed in a different direction.
