Not to burst any bubbles, but the Vedas contain the same information, and were composed some time between 3,000 and 7,000 BC. The Gathas have similar things, perhaps as early as 4,000 BC. There's a tribe out in Columbia that knew about space etc. despite not having contact with the West until about 1990. They even knew stars that can't be seen by the naked eye, and could accurately point to where they were on photographs of the night sky. I presume most ancient cultures had this kind of knowledge, but the knowledge was restricted to a priestly class following the "agricultural revolution" (the "scientists" of the day). Earlier cultures probably had even more widespread knowledge of e.g. the spherical nature of the earth, considering that they were all prime astronomers (talking meso/paleolithic here, when they were building stone calendars all over the place).
