Any sufficiently advanced technology would seem like magic to the less advanced.
That's a saying that's often abused. There is, in fact, a fundamental difference between technology and magic, in that the former is constrained by the fundamental laws of physics. Not to mention that we're talking about biology here, not technology.
How do you know
we're not talking about technology? Ra's sarcophagus raised Jackson from the dead and fixed his fatally wounded girlfriend. How do you know it wasn't also capable of merging two humanoid beings so that one's consciousness can supplant the other's?
You don't, because it was never addressed in the movie and the series retconned Ra's race into a bunch of eels so we can have dramatic shots of slippery green phalluses jumping into people's mouths to take them over.
I guess that depends on what ideas you define as silly. We disagree on which. Not a shock. As much as I loved SG-1, it has always fallen short of the quality of the movie in my eyes.
Bull. All they really did was pick new mythologies to turn into aliens, which is just the movie in multiple.
And all the producers of the show did was tack on more ancient cultures using the same ancient astronaut trope! They even had a race frigging called THE ANCIENTS!
One without which the TV guys would have had nothing rework.
To you. I thought it was great. I enjoy it every time I see it.
What impresses me so much about the TV franchise is how they managed to take such a shallow foundation and build such a rich and imaginative universe upon it. I daresay it's the only SFTV universe that can compare with Star Trek for sheer scope, richness, and coherence. In some ways it's even more coherent than ST managed to be, since it remained mostly under the same creators' control throughout its tenure. (Although unlike ST, its short-lived animated incarnation is unambiguously non-canonical.)
The series is better than Star Trek. I've said it before and I'll keep saying it.
Doctor Who's universe certainly has scope and richness, but coherence has never been one of its features.
Yet, it has been on for decades, and its fans generally don't give a shit if it makes any kind of rational sense.
