''Adam never existed. Adam was created by god, therefore his existence was never proven. If you have learned that at Beauxbatons, then I am truly afraid of what I am going to hear next. It seems that your Muggle Studies professor there did not understand the subject as it is - scientifict, therefore excluding any religious and unproven evidence about any event in our history. If it were up to religion, our planet would still be flat and we would all be created by god, without evolution. Which is utter nonsense. But, seeing that it probably is not your fault, but the fault of the idiots ad Beauxbatons, I will give you a second chance to answer this question. The person I am talking about may not be the oldest or the first, but it is the oldest Muggle that we know about, therefore treated as the first, until they discover someone older.'', Wilson said.
He then stood up to stretch himself. ''Again the names. You really have an issue regarding that, Miss Izzy. And, to answer your question fully. I am, through years of experience, immune to the external charms of Veelas and can detect the majority of love potions known to man, which makes me immune to any love charm, including that of the Veelas. They are beautiful, but with a skilled wizard, like there are many I know, their effect and charms have no use. Which is what I have been talking about the whole time. Beauty and grace, in the presence of a skilled and intelligent wizard, have no use and are only useful in a desk job. This is why I find the professors of Beauxbatons incompetent, and the professor here in Hogwarts competent. There, they raise models, here, they raise wizards and witches. Do you need any further explanations, Miss Izzy?'', he added sitting back down.
