By testing for, and examining, such evidence as would be expected from whatever phenomenon is under investigation. You are seriously misunderstanding what observation means in a scientific context. It doesn't mean you have to be able to see the cause with your own eyes or else it isn't true.
Thank you for saying that. We look at what would be expected if either hypothesis were true. Now go look back at my other response to you, and tell me which one has better predictive power.
