Is this world truly an illusion or Maya as The Gita states?

One often wonders what the world being an illusion means and the rational mind seeks a scientific explanation for these eternal truths.Illusion or maya means something that is not what it seems to be or deception.Now, if we look at our world everything from plant, animal, rock, wood, metal to humans is nothing but atoms of various elements arranged in different combinations. Water is two atoms of hydrogen and one of oxygen and carbon dioxide is one atom of carbon and two of oxygen. Similarly, every substance is a combination of different atoms. If we enlarge an atom to the size of a room then the nucleus is nothing but a speck barely seen by the naked eye. The rest of the space in the atom is empty except for the subatomic particles electrons revolving around the nucleus.So, at the atomic level everything in our world seems to be vast empty space with energy (as the basis of interaction between atoms is electrical energy) and has no defined concept of physicality or form. Therefore, a table is not really a table if we take it apart to the subatomic state and the same holds true for us humans and other things.Then doesn't the statement that this word is an illusion stand true?
