because i watch more than one on a subject matter
and one of them said what is now Ethiopia was the first lad out the waters
MR.Blueprint, it is well understood that water was probably there when the Earth began, although not in the form of oceans. In other words, water has existed here for billions of years. Without a doubt, when oceans first formed, the continents as we know them now were considerably different. You know this as well as I, so I won't descend into a diatribe on geological history.
The salient point is, the land area we know today as Ethiopia did not exist—but extant land masses billions of years ago pre-existed oceans. That said, I think it's futile to say which "emerged" first from the oceans, since land pre-existed the oceans.
With respect, I might posit that the video you watched was put together by someone with an afrocentric bent. This would make it as devoid of reliable educational information as anything cobbled together by some eurocentrist.
I couldn't agree more with The_Spartan: YouTube is for entertainment, not education. I quite enjoy YouTube videos for their source of entertainment but find the vast majority of them quite lacking in educational merit.
