Can anybody tell about the expedition of rata and maui that reportedly took place over 2000 years ago?

Answer 1

From 21st Century Science & Technology Magazine:

"Around the year 232 B.C., Captain Rata and Navigator Maui set out with a flotilla of ships from Egypt in an attempt to circumnavigate the Earth.1 On the night of August 6-7, 2001, between the hours of 11 PM and 3 AM, this writer, and fellow amateur astronomer Bert Cooper, proved in principle that Captain Rata and Navigator Maui could have known."
