1. OK, not an invention but curiosity. Without it, nothing of the above.. I know this one is cheesy and breaking it but I still feel it deserves a good place here.
2. Written language, first way to communicate.
3. Internet, no internet no all you interesting people here!
4. Computer, neede all though I usually sit swearing at them most of the day..
5. Microscope, to see and find out more about what is in there instead of out there
