Who first discovered pi?

Maybe it was just always there

idk, but I love eating it!,...

and using it so I don't get to fat!

I would guess that some one got a whole bunch of circles and then measured the cucmfrance, after this they measured each ones diameter. with these two they came up with a value that was universal among all circles when multiplied by the diameter. as i said thats my guess probably not right but eh
