Math proofs are also 'discovered'. Another interesting thing to think about is cosmic rays are far stronger than anything we can create in a particle accelerator, but the current flow in an accelerator is a zillion times the intensity of cosmic rays, so thats why we build particle accelerators to "discover" things that already exist in cosmic rays. Technically there are some atoms of this "stuff" in a lump of uranium ore, well, a big enough one, anyway, but it would take much fancier instruments to detect and manipulate it, its easier to make lots in close proximity to a detector.
