Not according to history and archaeology.The "earliest deity in history" communed with Adam. Yahweh/Jesus.
As I pointed out, the god of the Tanakh, Yahweh, doesn't appear until 1500 BCE or later. The Sumerian goddess Inanna we can place in the 3rd millennium BCE, along with the other gods of Sumer, and the gods of Egypt.
We also infer religious practices at the Çatal Hüyük civilization in Anatolia (now in Turkey) which dates back to 7000 BCE, but we don't know which gods were involved. (There are some fairly strong clues that a major deity is the same god as worshiped later in the Minoan culture on Crete, whose symbol was a bull.)
And there's the excavation at Göbekli Tepe in Turkey, a religious center dated to 12,000 BCE, but again we don't know the gods involved. One photo on that link shows a pillar of square cross section with a bull carved on it. Roughly that shape of pillar, often with bull's horns one on each side, and painted red, is found in Çatal Hüyük and on Crete.
