Don't forget agriculture, which was the end of tribal communities, and the beginning of trade between communities.
I like the printing press too. A major change to the world.
The steam engine was right up there, for having started the Industrial Age.
But the Apollo Moon program, is going to be on the top of my list, it happened in my lifetime. And in terms of degree of difficulty, it gets max
points. Where other achievments in history, were quickly followed by other similar advances, reaching the moon was unique, and has not been duplicated
so far. It's uniqueness, is that it required a very large group of people to make it happen. That is something that doesn't happen very often.
All four of these promoted change throughout the world. Changes that are permanent, and not fading away.
I didn't include the computer, I still see it as a spin-off of the Moon program, and it's not really something the entire world population takes
advantage of. Not yet, although computers certainly effect almost everyone in the world, in one way or another.
