We don't know. It could be finite; spatially infinite is just the assertion and consensus using the best current model, LCDM. That was my initial understanding and the reason for starting this thread. @PeterDonis is saying that the phrase "space was created" is not well-defined, so it is hard to talk about and could be a meaningless statement. Mind bending, isn't it? I personally think that there is still a flaw in the logic of spatially infinite, but it is really hard to pin down when trying to conceive of something so foreign to the perception of time and space our minds are used to. Part of the problem for me is going from mathematical abstractions of geometry and scalar expansions of coordinate systems to describing what the physics is trying to model.
