Nope, your screed is that its impossible for it to be contemporary humans, and need to be rebooted. It can be. Stargate Earth has never been totally "US" and my 5 minute think can make it Contemporary to us modern humans in the show and not be Trek Lite.. so I'm 120% in the Revival camp as a reboot would just rehash way to much. EDIT: Okay, how about using a possibility from the Stargate Film sequel. Daniel Jackson, or somebody, finds Another stargate on Earth, not connected to the current gate network, but one that maybe connects to the gates that the Destiny seed ships have settled in other galaxy's or maybe a whole new network by different ancients. To far to fly with ships, so its back to the gate style, and still being based on Earth. Ta da!
