What did Neil Armstrong mean when he said, "That's one small step for a man, one giant leap for mankind."?

Answer 1

That he (one man) was taking a small final step down the ladder to put his foot on the moon.  However landing on the moon marked a monumental first for mankind (the human race)

Answer 2

It only took one small step for Neil Armstrong to step onto the moon, but this was a great achievement for mankind so it was a giant leap in technology and exploratory advancement.

Answer 3

Sorry, but the meaning seems quite obvious.

Answer 4

That his step was accomplishing a monumental goal representing a high point in mankind's accomplishments

Answer 5

He meant that it was a small step taken (for him to step off the space shuttle), but a giant leap for mankind, because they had accomplished space travel/landing on the moon.

Answer 6

exactly what it says he took a small step physically but for humanity it was an enormous leap forward

Answer 7

He screwed it up, he was supposed to say

"That's one giant leap for man, one small step for mankind"

..but then again, everyone gets nervous sometimes, even astronauts!
