If you had to name the most IMPORTANT historical event of your lifetime, what would it be? Believe it or not, there actually IS a consensus answer.

According to a new survey by the History Channel, 76% of people say the September 11th attacks are one of the 10 biggest events of their lifetime. Nothing else even got 40% of the vote. Here are the top 10 . . .

1. September 11th.

2. PRESIDENT OBAMA getting elected.

3. The tech revolution.

4. The JFK assassination.

5. The Vietnam War.

6. The wars in Iraq and Afghanistan.

7. The moon landing.

8. The fall of the Berlin Wall and end of the Cold War.

9. The legalization of gay marriage.

10. A tie between the shooting in Orlando and the Gulf War.

Obviously, your answers are going to depend a LOT on how long you've been alive.

The survey also split the results into four different generations: Millennials, Gen X, Baby Boomers, and the Silent Generation. September 11th was the top answer across the board, but after that it varied wildly.

Millennials had Obama second and had gay marriage fourth. They also had events like the Columbine shooting and Sandy Hook.

Gen X were the only ones to include the Challenger disaster.

Baby Boomers had the JFK assassination second and the Vietnam War third. They also included the Civil Rights Movement.

And the Silent Generation had World War Two second on their list.
