How we come to have the world-views we do is an interesting question. No doubt reason plays a part, but human needs for meaning and purpose are usually more important. At times personal taste may be what decides the issue. There is nothing to say that, when all the work of reason is done, only one view of the world will remain. There may be many that fit everything that can be known. In that case you might as well choose the view of the world you find most interesting or beautiful. Adopting a world-view is more like selecting a painting to furnish a room than testing a scientific theory. The test is how it fits with your life.
