There is the "lost cosmonaut" conspiracy theory.
This claims that Gagarin was the first man to survive space flight and land back on Earth successfully and alive. The "lost cosmonaut" theory is that there a number of other manned spaceflights launched by the USSR before Gagarin's flight (perhaps as many as 14), but that these all ended in failure, the space craft exploding, the astronauts dying in space or being dead when their spacecraft landed on return. For political and propaganda reasons (as this all would have taken place during the Cold War) the USSR government covered up all these failures, only going public with the Gagarin mission because he returned alive and well.
So, if any of this were true, Gagarin would not have been the first man in space, only the first man to successfully return alive from space flight.

Are you seriously asking this question, or is it just another fabrication to make Americans look stupid?
I realize that the American Education system has taken a down-turn since the first batch of Vietnam War Draft dodgers got out of teachers' College, but the EXTREMELY Left leaning Teachers Union in the U.S. would NEVER give up a chance to put the information out there that the Capitalist in the U.S. were out-done by the Communists.
