The difference is that atheists feel less tempted to claim that thermodynamics invalidates the Bible.
This atheist doesn't feel that evolution, geology, or astronomy invalidates the Bible. However, it does invalidate creationism, which isn't the same thing.
Also, when the scientific theory of evolution first emerged it wasn't presented as invalidating the Bible. It was the theists, creationists in particular, who decided that evolution invalidated the Bible.
I have used this quote before, so I apologize if this is somewhat redundant.
"It can hardly be supposed that a false theory would explain, in so satisfactory a manner as does the theory of natural selection, the several large classes of facts above specified. It has recently been objected that this is an unsafe method of arguing; but it is a method used in judging of the common events of life, and has often been used by the greatest natural philosophers ... I see no good reason why the views given in this volume should shock the religious feelings of any one. It is satisfactory, as showing how transient such impressions are, to remember that the greatest discovery ever made by man, namely, the law of the attraction of gravity, was also attacked by Leibnitz, "as subversive of natural, and inferentially of revealed, religion." A celebrated author and divine has written to me that "he has gradually learnt to see that it is just as noble a conception of the Deity to believe that He created a few original forms capable of self-development into other and needful forms, as to believe that He required a fresh act of creation to supply the voids caused by the action of His laws."
— Charles Darwin, The Origin of Species (1859)
It is interesting to note that some Christians even had a problem with Newton's formulation of gravity where it is portrayed as machine-like, removing God from a place of power over nature.
Consequently, the adjective atheistic is never implicitly present when thermodynamics is mentioned, and there is no corresponding need for the "theistic" qualifier.
It is also worth mentioning that creationists use malformed ideas about thermodynamics to try and disprove evolution, but that is probably a topic for another thread.
