You said something important here Nosyned.
You said the person in the field can only claim hypothesis or speculation if the theory fails because of the method failing.
Well Percy has tried to tell me otherwise. That theory and hypothesis are only of degree of difference. That hypothesis is the same as theory.
This is an important point and shows the importance of definition of words and concepts.
When I refer to origins I only mean any subject that deals with explaining the past. I don't mean the origin of life itself.
