Why live in a kingdom of hallucinations?

Although atheistic men like to enjoy material opulences and they endeavor with great energy to build big residences, roads, cities and factories, unfortunately they cannot live more than eighty, ninety or at the utmost one hundred years. Although the materialist exerts so much energy to create a kingdom of hallucinations, he is unable to enjoy it for more than a few years.
