I have experienced some odd "supernatural" things that I cannot explain by means of science, but that does not mean that I have to believe in a creator. It just means that there are things happening that I do not have an explanation for.
There may be an existance after death, but this also does not explicitly require the services of any superior being or creator.
We'll all find out by experience or the lack of it one day.
Although I have heard and seen some unexplainable things, they did not confirm the continuance of existance of a particular person.
