Because it fits the occultism theme:
Stargate is Soft Disclosure and uses a sheme which we find a lot in the media. But before I explain the sheme let us go into just how the Stargate series is real:
So, what is the Series about? The egyptians created the Pyramids long time ago as a landing hub for Aliens which are the egyptian gods. I assume you know my stance on what we are shown to be Aliens to be actually spirits if you read my other posts so I dont go over that again now, but this is the same case. The egyptian gods instead of spirits being aliens. Now we do know the Pyramids are able to focus energy and are aligned with /tuned into the stars aka the heavens.
For example:

Also could relate back to focusing spiritual energy.
Just for completion some other weird stuff around the Pyramids

I believe the Pyramids are a kind of sensory deprivation chambers that focuses your mind towards the heavens where they met their gods through astral projection. In the series they then went to the stars where they encountered various entities, among them the Goa'uld, reptillian/serpentlike beings that take control of your body.
