well maybe they were really good housekeepers.
its obvious that this site shows several structures that
date to apx 175,000 years ago.
and people living in a cave during a glacial period might pay
more attention to their living quarters because they like it.
and there may have been rules set up withing their local
governing body that required the people to keep the place
clean , after all they had already been living in there
for a thousand or so generations.
they may have noticed after the first generation that they
would have to keep the place clean or the smell of the rotting
debri would make life unbearable and that the debri would pile
up forcing them out of their living quarters.
there is also the possibility that water may have washed the area
clean of debri as the ice melted.
just because the archaeologist supposedly havent found any
debri doesnt mean that the people who constructed the structures
didnt live there.
these people would not have wasted any debri that they may have
had , they probably would have eaten every part of any animal
that they killed for food or used the unedible parts to make
tools or jewelry with.
they couldnt afford to be a pessimistic group of people sitting around chanting woe is me , they had a really hard and rough life
in front of them.
they had to keep busy and that is why there is no debri would
be my guess.
I think they did a very good job of constructing the home and
animal corrals and hearths and keeping the place clean.
its odd to me that the archaeologist always want to make the
neanderthals look as if they were real dumb asses , I would
like to see them do any better in a 90,000 year glacial period.
they might last a few weeks before they died of starvation.
if they were really smart.
