Here is a video by a scientist being interviewed about the age of the earth.
Appeal to authority.
"Scientists say" lots of things, about lots of things, the global "climate crisis" and mRNA vaccines to name a couple more recent examples.
E.g. I heard a "scientist" say if we stop burning fossil fuels we can stabilize the climate. Evidence however indicates that the climate hasn't been stable for as long as the Earth has existed, however long you may think that may be.
Evidence is more important than what "scientists say".
