Once more. Mark was born in 1965. He claims to be the dark boy. Both images were from the same day. In his most recent book, Mark claims they were from 1971. In 1971, Mark would have been six years of age. How old do you think the dark boy is in that photograph? Two heading towards three?
Darker boy I’d guess no more than 3 to at most 3 1/2, lighter boy at most 2. It’s obvious they are not related or if so (which they aren’t at all, as we know), very distantly so. IMHO the darker boy is possibly a bit big for his age, more strongly built.
And of course the top photo is shopped to make the dark boy’s head unnaturally twisted in an anatomically impossible position.
Reminds me of how liars often embellish lies with unnecessary details, this is often a “tell”.
Now this photo is said to be from 1971, that is not a 6 or 7 year old boy in my view. Mark is trying to make it so the boy on the left can’t possibly be Zero. Darker boy doesn’t appear have Mark’s hairline, oddly enough....
