Is There a Correct Use of Stone Age, Bronze Age, Iron Age? · Early human remains found to carry R1b · Would Proto-Indo-European Diverge Into Hittite, Mycenaean Greek, Indo-Aryan in The Biblical Time-Frame?

First we rule out Maykop culture. Quotes will consistently be from wikipedia.

Maykop culture, c. 3700 BC – 3000 BC
New data revealed the similarity of artifacts from the Maykop culture with those found recently in the course of excavations of the ancient city of Tell Khazneh in northern Syria, the construction of which dates back to 4000 BC.[citation needed]
Radiocarbon dates for various monuments of the Maykop culture are from 3950 - 3650 - 3610 - 2980 calBC
According to genetic studies on ancient DNA published in 2018, the Maykop population came from the south, from Imereti, and was descended from the Chalcolithic farmers known as Darkveti-Meshoko who first colonized the north side of the Caucasus. Maykop is therefore the "ideal archaeological candidate for the founders of the Northwest Caucasian language family".

So, Maykop presumably spoke Northwest Caucasian.

Second, we line up cultures that lead up to Yamnaya culture / Afanasievo culture (apart from Maykop). We also line up very early Indo-European languages at the very end.

Starčevo culture, circa 6,200 B.C. — circa 4,500 B.C.
Vinča culture, c. 5700–4500 BC
Linear Pottery culture, c. 5500 BC — c. 4500 BC
Boian culture, divided
Phase I – Bolintineanu Phase, 4300–4200 BC.
Phase II – Giulești Phase (also known as the Giulești-Boian culture), 4200–4100 BC.
Phase III – Vidra Phase, 4100–4000 BC.
Phase IV – Spanțov Phase (also known as the Boian-Gumelnița culture), 4000–3500 BC.
Cucuteni–Trypillia culture, is divided
• Early (Pre-Cucuteni I–III to Cucuteni A–B, Trypillia A to Trypillia BI–II): 5800 to 5000 BC
• Middle (Cucuteni B, Trypillia BII to CI–II): 5000 to 3500 BC
• Late (Horodiștea–Foltești, Trypillia CII): 3500 to 3000 BC
and is influenced:
The roots of Cucuteni–Trypillia culture can be found in the Starčevo–Körös–Criș and Vinča cultures of the 6th to 5th millennia,[7] with additional influence from the Bug–Dniester culture (6500–5000 BC).[21] During the early period of its existence (in the fifth millennium BC), the Cucuteni–Trypillia culture was also influenced by the Linear Pottery culture from the north, and by the Boian culture from the south.[7]
Sredny Stog culture, c. 4500 BC – 3500 BC
The culture ended at around 3500 BC, when the Yamnaya culture expanded westward replacing Sredny Stog, and coming into direct contact with the Cucuteni–Trypillia culture culture in western Ukraine.
Repin culture, 3900–3300 BCE
Anthony suggests that the Afanasievo culture was formed by a migration of people with a material culture of the same type as Repin, probably from the middle Volga-Ural area c. 3700–3500 BCE.
Yamnaya culture, c. 3300 – 2600 BC
Afanasievo culture, 3300 BCE — 2500 BCE
Hittite language, attested 17th to 12th centuries BC
Mycenaean Greek, 16th–12th century BC

Note, I cannot take Mitanni as earliest attestation of Indo-Aryan, since the language they actually spoke was Hurrian, with some Indo-Aryan superstrate, if that was the case.

But from Starčevo 6200 BC to Hittite 1650 BC, no problem. 4550 years.

From Yamnaya 3300 BC to Hittite 1650, still no problem. 1650 years.

Third, here is the problem, in a Biblical time-frame this is shorter. I will now add quotes from my New Tables into the mix:

2309 - 1521 = 788 years. Bad. Even if you begin with Starčevo culture
2086 - 1521 = 565 years. Worse, and you have begun with Sredny Stog.
1868 - 1521 = 347 years, from beginning of Yamnaya culture to appearance of Hittite.

Add another 100 years each for coming to Mycenaean Greek.

This is why I tend to feel a YEC is basically committed to Sprachbund type of group for Indo European./HGL

PS, this is consistent with, but may not closely correlate to, the earliest Aryan vocabulary of the Mitanni being in the non-IE language of Hurrian. As mentioned above, also sourced to wikis on Mitanni and on Hurro-Urartian languages/HGL
