Outter space

Is ouster space truly infinite if so are their places that the GFL hasn't discovered, planets and beings they have no knowledge of . Do they have the ability to scan all of space to map it out and know if their are planets and beings that are out their yet for them to reach? How was the universe created? Do they have a theory or store like the christian/catholic bible says?who are the most advanced civilization in the universe now? Who's the oldest living?
