You are being hysterically funny with the penicillen and electricity. That is like saying the lightbulb wasn't invented because god made light.
No, my point is that both were naturally occurring, not inventions. You may as well claim that Newton invented gravity. The lightbulb was a physical invention, not a discovery of a natural phenomenon.
