Exactly. If evidence comes forward that completely falsifies evolution then we are back to square one, which is “we don’t know”. Where science is concerned, the default position is not “God does it”. Some would argue that the default position in science is “nature does it”, but that is too simple of a picture IMHO. What science defines as natural is mehcanisms that operate in our universe and produce measurable changes in our universe. In this case, humans are natural. If God resides within the universe and causes change in our universe then God is natural as defined in science, at least in my estimation.
