UrRong - Parallax is not only something that makes intuitive sense, but it is also a phenomenon that is based in logical sense. The idea behind parallax is rooted in geometry, specifically the concept of the angular displacement of an object based on the observer's perspective. When an object is far away, it appears to move more slowly because its angular displacement is smaller than an object located nearby. This is why a plane flying at 600 mph across the sky will appear to move slower than an old granny walking by a porch at 1 mph. It's not hard to explain why this concept is true - it's because of basic mathematical principles.
