Read the last sentence of the article. Bias warps perception. This shouldn't even be posted here.
I don't understand - is it unexpected that the person forming an argument for the alien hypothesis has written a book about it? That's not usually what people mean when they say "bias", and it's even further from being a good reason that the entire article "shouldn't be posted here". Or are you just making the assumption that the book's dumb "clickbaity" title must mean the author is full of shit?
