Answer:
Observability, Consistency, Natural explanation, Predictability, Testability, Repeatability, Falsifiability
Explanation:
A supernatural view about the origin of the earth or probably life on earth would not agree in anyway with a scientific approach.
If we are to approach the subject of origins scientifically, usual characteristics of scientific methods would be crucial in making logical conclusions from the process. One would need to carry out succinct observation about the procedure highlighted in the study. Then proceed to formulate a hypothesis. Hypothesis scientifically must be testable, repeatable and falsifiable. From this, an experiment can be set up to carryout more detailed observation. Explanations can then be drawn from patterns noticed in the process. The conclusion must be consistent with other scientific principles already in place and it must be a natural reason.
A supernatural explanation would be based on a belief system that might even contradict known facts and observations.
