With hominids to Modern homo sapien representing only 125k years of geologic history, and what we know of ocean levels--let alone existing technology at the time, such is incredibly doubtful. The only chance for this to have happened, it would be an unexplored part of the ocean--but even at a time when such place could have been settled, it predates the technology that allowed civilizations to prosper and develop such technologies by many thousands of years.
The most likely scenario, however, is that we discover that the civilizations we do know about were far more advanced than we give them credit. Greeks, Mayans--plenty of highly successful cultures, either well documented or not, are turning up technologies that we never thought possible at that time.
It's easy for such records to be erased when all such knowledge is kept in one place and burned down, or the "god du jour" sweeps in with his newly-saved followers and proceeds to erase all presence of these godless savages and their evil witchcraft.
such is the folly of man.
