Please don't use the phrase "believe in" with regard to either of those demonstrably factual events. One may "believe in" a deity or deities of their own choosing, as such things are not rigorously demonstrable by direct observation and measurement, whereas the two you mentioned certainly are amenable of such.
By using the term "believe in" you allow yourself to be sucked directly into the religious fundamentalists mindset and world view.
There is a fifth dimension, beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity.
