Space, we must acknowledge, is essentially an intellectual construct. We understand it to be there, even if we experience it as a void, an absence that we cannot see. Space is always the implication of objects. For an object to exist, we think, it needs some kind of space. So, the first space we can imagine is the space occupied by objects. In order to see an object we must be separate from it. A space must exist between us and the object. Therefore, we imagine a space around the object, and also around ourselves, because, at some primary stage in our mental development, we realize that we too are objects. Space is the medium of our relationships with the world and everything in it, but, for all of that, we do not yet experience it in a palpable sense. We must think space into existence.
