I would like to take the writer seriously but although he identifies himself as a scientist, I can't seem to find what his credentials, affiliation or even his specialty are.
What's the difference? Even if he's your newspaper boy, his explanations were simple and logical enough for anyone to understand.

Mainly because his "explanations" are so simplistic that they are scientifically useless.
