Moebius (1)

SG-1 and General O'Neill use the time-puddle jumper to go to Ancient Egypt to recover a ZPM. They successfully steal it but they find Jaffa surrounding the cloaked jumper. The future is altered and SG-1 never existed - Daniel teaches English as a second language, Carter proofreads astrophysics papers, and Jack retired from the Air Force and became a charter boat captain. Archaeologists find the video camera Daniel took with them with instructions to find the stargate, find Teal'c, and return to the past to correct the future.
