De soluções do Stargate SG-1 :
The SG-1 team travels to the planet Bedrosia where, unbeknownst to them, the planet's two cultures have been at war over their opposed beliefs regarding the Stargate. Upon their arrival, they are met by the curious Nyan, a scientist. Nyan explains to them that their arrival through the Stargate proves that the beliefs of his rival culture, the Optricans, is true and that humans were brought to this planet by aliens through a gateway. His culture, the Bedrosians, believe that human life evolved without a gateway and was created by their god, Nefertum.
The team's arrival is soon detected by a group of Bedrosian soldiers and their leader, Rigar. Colonel Jack O'Neill, Major Samantha Carter, and Dr. Daniel Jackson are captured, while Teal'c and Nyan narrowly escape. During his escape, Teal'c is blinded. Rigar cages his three prisoners and interrogates them as to how they arrived on his planet. He believes that they are Optrican spies, when they insist they traveled via the Stargate. Rather than face the possibility that the entire belief system of his people is wrong, Rigar chooses to destroy all evidence, including SG-1. Though blinded, Teal'c with Nyan's help must outwit the Bedrosians before Rigar can execute his plan.

Teal'c: Nefertum was an under System Lord to the one named Ra. It is with him whom I did battle.
Nyan: I don't understand. Nefertum was and is the creator of all of us. He created this planet and this great continent.
Teal'c: Correction. Nefertum was an alien who most likely brought your people though the Stargate as slaves many thousands of years ago.
Nyan: That is what the Optricans say.
Teal'c: They are correct.
Nyan: Oh dear Nefertum, this is blasphemy. If it is true, it could change everything. I must show my colleagues at the research academy.
Teal'c: Can you be certain they will believe you?
Nyan: They are scientists as I am. They will realise they are wrong when presented with the evidence.

A cotação que o OP estava procurando é:
Teal'c: Then perhaps you would be better off if I were no longer alive.
Nyan: Teal'c, I'm a scientist. When I find evidence that my theories are wrong, it is as exciting as if they were correct. Scientific advance in either direction is still an advance.
