Aside from a lot of the wildly baseless assertions and errors made that I can address at another time (since this post is piss-long), I’ll reply to the part that mainly concerns me;
I used the density of bedrock, which encompasses the whole first layer of Earth (crust), all of which relates to peeled off mass that I calculated the KE of. Using Earth’s mean density is completely nonsensical, since this MEAN is derived from taking into account all layers, including the Earth’s core. The ejected mass from the bottom is solely from the crust. Unless you can viably prove the majority of it is from the other layers; not only that, but evenly distributed between them to have a mean density of 5514kg/m³. I doubt there’s any one part of the planet (in any of the layers) that’s exactly 5514kg/m³, which makes your usage of it even more redundant than it already was.
Again, if no one else would like to address the rest of this post, I could at a later date. Most of the WoG stuff here is what I found initially and outsourced to
this dude on CV, so I might find it easier to refute some of them.
