"f a scientific theory is not true in every instance, can it be said with any certainty that it is true in any instance? If Evolution cannot explain the origin of every species, why are you so certain that it true about the origin of any species?"
Because it's scope doesn't include the origin of life, and never has? How difficult is this for you to comprehend? It doesn't explain quantum physics either. Is that a deficiency in the theory?
Pretty difficult, actually. I believe that the very first living thing was a species, bless it's little heart. Don't you kind of feel sorry for it, all alone out there with no explanation )-;
It doesn't explain quantum physics either. Is that a deficiency in the theory?
No. That would be an imaginary deficiency. There are enough real deficiencies to worry about. :-)
