YOU CAN NOT KILL LIFE!
There was no proof ever that His Majesty died. No bones, no DNA proofs, no medical certificates, no nothing. And that funeral was the biggest fake ever.
Of course His Majesty had children, his first born was Asfa Wossen and his grandson should be the Heir, Zera Yacob. But the duties of the heir DURING THE LIFETIME of the Emperor is only representative(read it in the constitution). Now they want to sit pon HIM throne... call themselves EMPEROR IN EXILE (What's that?) and things like that. And still we look to Ethiopia and see no one sitting pon King David Throne coz it is still HIM sitting pon the throne and as long those children do not respect that, they will never again reign over Ethiopia.
Bloodtests? With whom? I guess it's rather hard to get one of the biblical royals for bloodtests, nah mean? So how could you compare HIM's blood to the blood of the biblical Kings? All we can do is trace the line back through history and science. And of course biblical logic and evidence.
What we know is that HIM was direct descendant of Negus Sahle Selassie and that one was the head figure of the Southern Solomonics. Everything else is shrouded in history.
