Well, what beyond science is truth for you? Can natural occurrences alone account for everything?
Can natural occurrences explain how planes fly?
At one time man thought not. Then we learned those principles. That is science. To take us in the direction of knowledge, not to shut us off to "God did it". If we took that attitude, you would not be posting tonight. More than likely your genetic train would have been broken long ago and you would not exist.
Can science study anything that isn't a natural occurance? Can you point to anything in physics, biology, astronomy, geology, or chemistry that isn't the result of assuming that phenomena are regular?
