Thank you for your question. The space between two objects is not an object, while at the same time it is filled with tiny objects such as atoms, microbes etc. An object is a 3 dimentional body, and the space between objects is the space between their limitations. However, just because it is not an object doesn't mean that it doesn't exist as part of the corporeal world. Existence is reality and so since the space exists it is real, even if we do not classify space as a body or an object.
May you always be successful
