As for the second, I am somewhat familiar with the picture. I don't know if this will be considered of value to you, but I'll share it anyway. Explained? As far as I'm concerned it's explained, but to each his own eh?
If you do find more regarding picture 1, please do post it.
Well, I'm 100% certain that DBunker was only posting these "ancient alien" pictures as a joke, since he always says that everything related to UFOs is pure nonsense.
I'm not foolish enough to go out on a limb and pretend that I know enough about the Stone Age and ancient history to even begin to talk about these periods intelligently. That Egyptian picture does look different when it's in sharper focus, so it is actually a vase of flowers.
This is DBunker's link to the "UFO Cave Paintings".
And if you click on that particular picture it links to this website.
