That is one of the things I’m uneasy about with shows like Stargate, despite how much I enjoy them.

Instead of just discovering the aliens on other worlds, or arriving in the present time, somehow they were here all along. Instead of humans creating and advancing civilization on their own, they were at best guided by outside influences with vast resources and technology advanced beyond what we even have today.

It also means basing your sciencey story on blatant lies.

I dislike it more when it’s a part of time travel stories, where you basically have your main characters go back to take personal credit for something that real people actually did.
