Question about Stargate, Ra? help me please?

I have a question about Stargate The Movie (1994) . On the other
planet, where the Ancient Egyptians were enslaved by the alien/Ra.
Some people said that the alien was pretending to be Ra/The Sun God of
Egyptian, but some think that the alien was Ra. He was Ra and forced
the people to worship him. which one is your opinion? Did the alien
create Ra for himself or he was pretending to be Ra to make the people
on the planet working for him. I think the alien was Ra, he was the
Sun God because he came to earth earlier and create the civilization.
so he must have created Ra for himself as well. what do you think?
