That would be a nope from chief. My understanding is that the earth has always been in the Goldilocks zone. I think you're severely underestimating the time it would take for the Goldilocks zone to move far enough so that earth is no longer within it. We would definitely know if we changed planets; that is not something that would fly under the radar.
