Inventions.

How do people come up with some things? How on earth did they ever think of some of this stuff??... My friend and I were talking about things earlier, and we were trying to figure out how things came to be or how someone ever thought to create them. Okay, electricity.. Some guy stood outside in a storm, got electrocuted, BAM electricity.. How??? Like what did he do once he got electrocuted?.. Did he somehow harness that power and put it in a box to save and use? I don't understand. I don't think I ever will. Also, time. Who ever decided, "Hey, I think we should make something called a year and it should have 365 things in it that we should call days which would have 24 things in it called hours with 60 things in each of those called minutes and 60 things in that which would be called seconds.." Ummm, how do you invent that?? Or these math equations..OMG!! Why?? Who would sit there and be like, "I think I will invent a number called Pi and it will be 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679etc.." Can you say POINTLESS?! Yea, it is. Well, I just thought I would state my opinion on this. I want to invent something pointless and become a millionaire. Yup, I'm gonna do it! :)
