my wish is to see pictures with captions of the most ancient greek
sculpture, i.e. 5000BC or earlier if available.  I do not want to buy,
just look.  I AM A SCULPTOR.

The internet tells that greek sculpture began only after 1000 B.C. Are
you sure you want  images of sculptures 7000 years old?

Archaic period (8th to early 5th century BC)

The first period of Greek sculpture was heavily influenced by the
works of the ancient Egyptians. There was an emphasis on creating
perfection in human form. However, most of the statues created during
this time period appear very rigid and unnatural. They reflected a
body being assembled in pieces much in the way a mannequin might be
created today. Referred to as kouros and kore, these statues typically
stood very erect with their feet together and a blank stare on their
face. Despite the shortcomings, the Greeks were the first to create
free-standing statues during this period.

The Archaic period was the earliest period in Greek Sculpture which
started around 600 B.C. and lasted until 480 B.C.   These works have a
stiff and ridged appearance similar to that of the Egyptian sculpture.

Just to add to the previous comment--there was no "Greece" in 5000
BCE.  The first Greek speakers (proto-Indo-European) almost certainly
didn't arrive to the area until at least 2000 BCE, and some think as
late as 1500 BCE.  At 5000 BCE, the only "sculpture" extant would be
small figurenes from paleolithic (pre-agricultural) settlements, and
I'm not too sure much has been discovered in the area of modern
Greece.
