What is man's (in general not sexist) Greatist Invention?

[GAAN]

Or just Invention that you find amazing

Only Rule is you can't use one of the 7 simple machines

Wheel
Axle
Incline/Decline Plane
Wedge
Pulley
Lever
Screw  (and yes in this case the screw is a simple machine and I don't want to hear about how it is just an axle and an incline plane)

Concrete (or mortar...anything similar) is a good one as well. The Romans did a lot with unreinforced brick and mortar construction.

Steel is what really made humans the dominant species, both from building things...to killing things.

And before someone says we didn't invent bacon I offer this. Man had to domesticate the pig then invent the technique of thinly slicing and frying to a crisp.
