Telos and others thinking that they know the truth without actually researching the way things appear on the horizon and why would do well to watch this video:
Obviously it is not scientific to reject any postulate or proposal out of hand. "Condemnation without investigation is the height of ignorance", or as Aristotle put it: "It is the mark of an educated mind to be able to entertain a thought without accepting it."
This is the start of scientific investigation. It does no good to try to convince others, without first convincing yourself of what is true by comparing different postulates.
Too difficult to understand this? Let me put it this way: you don't get to truth by starting with your conclusion and then seeking only arguments in support of your conclusion. This is called rationalisation, and is a sure way for one to stay in their indoctrinated mindset.
