How much do the humans on absalom station know about aliens?

I have just started playing Starfinder, and I am thinking of making an Xenophile character who only knows what common knowledge there is to aliens refusing doing further research since she believes she cannot truly know aliens without actually meeting them.

Since my character will not have any training regarding aliens, what I want to know is how much does someone that is part of general public know about aliens in Starfinder universe? Is it to the level of knowing there are creatures out there that are not human without knowing any specifics, or are there lessons at high schools regarding alien culture and how to interact with them, or is there exchange programs for alien students with each student getting a non human?
