LOL at you thinking those long bones are ashes...
Bombsaway, where pray tell is the wood ash from the cremations? And how
exactly do you think the cremains were separated from it?
None of that addresses the hair and 'rubber implants' (I'm assuming that's a mistranslation of prosthetics) from the passage you shared, either, Bombsaway...
Look, you have tried to have this both ways before. If you are going to claim the bodies were obliterated, then you are going to have to come up with an explanation for how. The fuel requirement alone is massive. We are talking deforestation the likes of which the world has never seen in an 18 month window.
Even if you go with that, your alleged grave space, assuming every hole in the dirt is a mass grave, is wildly insufficient, at all of the camps.
We aren't even getting into the problems with testimony yet, we are only talking about physical reality.
At the end of the day, there are holes in the dirt that were dug for purposes other than consigning the dead, which is the point of this thread.
Even if granted, out of hand however, that every hole in the requisite area is a 'mass grave' they are woefully insufficient for purpose.
Look at the picture of 'grave 5' at sobibor I linked on page 1. You think that roughly shoebox sized bit of ash with the pony tails in it is 'bone ash'?
That's your claim?
Fine, then you have a few inches of ash in grave 5 Bombsaway, where's the rest?...
