Not all "gods" thought history were all powerful, some were very limited in their powers. not all "gods" were abrahameic.
But let's pretend that a good has to be all-powerful.
Then let's posit that there is a god that has created all life on earth by making sure that he preconditions for life on earth were just right and then leaned back and just wachted.
That is powerful enough, right? and while I don't believe that this (or any other) god exists, there is no logical inconsistency here.
