Why did Japan attack Pearl Harbor on the day when all American aircraft carriers left Hong Kong?

This is an "open plan" for the United States to obtain information in advance and evacuate the aircraft carrier from the port. The Japanese attack on Pearl Harbor was deliberately done by the Americans. In order to inspire the American people's anti-fascist determination (at that time, the American people did not want to participate in the war), according to historical data, the United States had obtained information from various channels at that time. The evidence has the following aspects. First, the aircraft carrier evacuated in advance, leaving only warships. Secondly, there were many medical staff near Pearl Harbor at that time, and they were said to be practicing medicine. The plane that confronted the Japanese plane also took off from the island near Pearl Harbor. Third, after the warship was bombed, it was quickly repaired and the parts were prepared in advance.
