<h1>What Is Real?</h1>
<p> In case tangible things, real is the thing that all people can see directly. For example, since 63 building is in Seoul and we can go to Seoul and see it, 63 building real. However, since we can't see alien anywhere, alien is not real. If all the people can see alien directly, then alien changes real. In case of formless thing, such as past people and event, if so many articles state and explain something, then that is considered real. In other words, reality is not absolute concept. Reality can be change relatively.</p>
