Or just talk to people like @lemouth in our community that are actual scientists. He works on the Large Hadron Collider.
I mean I know the scientific method quite well too and could have explained how it works, but if they want someone who might be better for an appeal to authority then @lemouth is a good example. Great guy too.
Only the large one? Pffff

I can make use of more superlatives if you want ;)
