But this is a big statement.
We frequently read and hear phrases such as “scientists tell us”, followed often by superfluous details of a larger tale. But rarely is an attempt made to explain how such knowledge is acquired. You know the type: “humans and fruit flies are 60% genetically identical” or “sea levels will rise X metres by the year Y.” But how do we know these statements are true? Do we know they are true? If no explanation is given, should we be surprised if many refuse to accept scientific consensus?
This, then, is for everyone who has heard something and sought to know more, who has shouted in frustration: “BUT HOW DO THEY KNOW THAT?”
So: 10 million years?
