A major disagreement between theists and atheists is the proper answer to this question: Does the universe have a purpose? When we approach this question from an empirical evidence first perspective, the proper answer must be no. Here is an entertaining 2 minute video recently produced by Neil deGrasse Tyson that answers this question from an empirical evidence first perspective. He places some emphasis on his not being "sure". Given that we are not omniscient it should be obvious that we cannot know with absolute certainty so prefixing and suffixing every strongly evidenced answer with "I am not sure" renders that phrase useless while attaching that phrase inconsistently to only some strongly evidenced answers makes it misleading. We all must be at least a little agnostic because we all are limited in our access to information. But he is clear in this video that there is a single best answer from the available evidence to this question.
