this is essentially the foundation of hut, it is unimaginable to see an actual house
structure right there next to what is now nothing.

Hasson's discovery is a striking evidence of human habitation,

"there are house structure consist of this: circle foundation with upright standing
blocks which are taken from the local bedrock, it would have made  a semi-circle
structure with properly skins and branchs and people would use it as a shelter"

he need to know exactly when they lived here,

-Ostrich eggshell beads

these ostrich eggshell beads are clearly human hand work,

they use the eggshell to make ornamental beads, cut into a circle so that a string
can pass through, so they string this into bracelets or necklaces.

the eggshells the beads were made from are also here, and provide the next clue,

the eggshells suggest, of course, there were ostriches, that's quite remarkable for
this environment to have animals like that.

this was no nomadic tribe but a settled farming community rearing animal for food

what we have here, it just be the evidence of a deep lake with mud deposited

this mud indicates a body of water, it could have supported a settlement of people

when the lake is deep as we can see from this layer as here, there would be a lot
of vegetation, a lot of animals, and people would have a good time.

at sites all across the sahara, scientists have exacvated similar evidence of life,
the remains of elephants, and gazelles, hippos and crocadiles, remarkable caves even
show people swimming, elsewhare human bones have been found, carefully buried in
what were lakeside graveyards, analysis these bones reals they date from between
10,000 and 6,000 years ago.
