The ancient Chinese were smart people and did worship a supreme being, ShangDi, who is a spirit and is the Creator of the universe. They truly honoured ShangDi and claimed that the Mandate of Heaven to the emperor was to respect Heaven and love the people (Image). Their leaders were chosen from those who were worthy to serve ShangDi and His people rather than by descent from aristocracy. It was during this stable political period that they invented the Chinese lunar calendar, boats, wagons, currency, and a time-tested political system.
An alleged problem appears when taking the biblical date of the Flood (2348 BC by Ussher) and man's ideas when Egypt began (3200 BC).
Traditional Egyptian chronology, which dominates modern understanding of ancient history, but is inconsistent with the Bible. When there is a discrepancy between traditional chronology and the Bible’s chronology, scholars usually ignore the Bible.
But if you've studied the history, rather than simply read about it, you already know that Ptolomy II commissioned a priest named Manetho to compile a history of Egypt. You should know that Manatho's chronology is known to be inaccurate. Moses has finally been found in the 12th Dynasty, for example, rather than the 18th where they were looking, and knew the Bible to be in error before. Because Manetho’s history contradicts actual Egyptian records from the time of the pharaohs, historians should not consider Manetho’s history authoritative.
Perhaps the proto-Hebrew texts dating back to the 11th century BC? That and other evidence suggest the Bible was written as events were happening since the Davidic period... Those same texts explicitly refer to the Books Of Moses pushing the books of Moses back to 1450 BC.
Parallel historical accounts are found in 500 civilizations around the world, many with no clear connection. Independent from the Bible, Noah's grandson Kush is specifically named as a post flood king in the Sumerian Kings list.
Then you have non-textual physical lines of evidence indicating a global event about the time (based on genealogies) that are consistent with the flood or the likely aftermath.
Since you are probably aware of Imhotep, you already know of the Great Pyramid, Mizraim, a Hebrew word translated "Egypt." Mizraim was Noah’s grandson, born to Ham after the Flood. So Mizraim’s descendants could not have built the Great Pyramid of Egypt (Mizraim) until after the Flood, and for that matter, after the events at the Tower of Babel that caused Mizraim’s family to move to the region of the Nile River. Further, as a geologist, I can assure you that the pyramids of Giza are built on the fossil-bearing rock layers from the Flood of Noah’s day
With all this evidence, the Great Pyramid is clearly post-Flood.
As to similarities with Gilgamesh and the Bible other than a flood (local in the epic) and a boat (small in the epic) there really aren't any! There are far more similarities in the Sumerian Eridu, Atra-hasis and the Shuruppak than in the Epic of Gilgamesh.
Actually the Epic of Gilgamesh dates to about 1050 BC.. References to the Books Moses wrote date to the same period about 1000 BC indicating first there were indeed texts written by Moses, and that those texts were known and fairly widely distributed by that time. If we examine the Genealogies we find that those texts by Moses had to be written no later than 1450 BC a full 400 years before the Epic of Gilgamesh.
