Yes it is, that is how we defined the term. I can show you that is how we defined the term and use it in science and everyday life.The defintion is not a fact. It is a definition. It is not a fact that a person with XY chromosomes is a male, because you can give no evidence for that. You do know what evidence is, right?
Is it a fact that standard acceleration of gravity (freefall) is measured at 9.80665 m/s^2 on earth? Is this not a fact because meters and seconds are just made up definitions?
