I can summarize Wilcock's position:
>He has super high level sources that he can't name
>He was specially chosen by good ETs to prepare Earth for disclosure
>There are hundreds of ET species, some good, some bad, some very bad, some are hybrid creations of the very bad
>The good ETs want humanity to stop warmongering and get spiritually ready to join the alliance
>We don't have much time as something BAD is happening soon
