Was Buddha a Scythian?

A certain monk, Vira Avalokita is trying to tell me that Buddha was a Scythian. He is using a book by Beckwith. Can anyone confirm this theory? I am thinking that Beckwith is wrong.

I think this person’s real name is James Beard. I have encountered him before and find that he is often banned from Facebook groups. I am now more inclined to distrust him. I am not trying to belittle him but I am interested if the Scythian theory has any validity.

Not likely to be true. Below some links about the topic:
