You don't need one, but the scientific method is misused far less often by those with science based degrees than those with GCSE or A level science education due to the different teachings you receive between the levels. It's not an absolute rule, but it's a good rule of thumb.
Indeed, but using other peoples facts to base your own opinion on a matter, does not make it 'incorrect' because you are not degree educated.
What a convincing retort, you don't fancy actually expanding it into a meaningful critique, do you?
I'm not going to sit here and decipher your entire post, because its using your own personal belief on how Science 'answers' questions.
..Unless you mean in general obviously
