Many physicists have pointed out the extraordinary ‘fine tuning’ of the physical laws of the universe that have allowed life to develop within the cosmos. Luke Barnes believes it gives evidence for a designer behind the cosmos, whereas Sabine Hossenfelder disagrees, questioning whether we can even speak of ‘fine tuning’ as a phenomenon. 

Is the nature of our universe evidence for a designer or can it be explained in some other way such a multiverse theory? Is it legitimate to use science as evidence for the existence of God at all? These and more questions get debated.
