But if the Guardians are the beings, and the Thargoids are a just one race of guardians, who's to say there aren't more? Look at humans - we are all the same creature but there are many different breeds. The guardians were a much more advanced race than humanity, even in 3303. There could be vast physiological differences in the different branches of Guardians, or they could look very similar but with different views and cultures. The Thargoids could have been just one of these, others may be peaceful or even worse than Thargoids. So you could be right and what we will see is a different alien, though I think they all come from the same origin.
