Humans begin to build a tower, hoping to reach God. At that time, humans were conceited enough to think that they could accomplish such a feat. So God, as punishment, collapses the Tower of Babel and makes the humans speak different languages in the different districts. They thus become unable to communicate each other.
神に近づこうとする人間たちは空へと向けて塔を築いて行った。神に手が届く。そう過信する人間たちの思い上がりを罰するため、神はバベルの塔を倒壊させ、人間たちの言語を地域ごとに分断し、互いにコミュニケーションを取れなくしてしまう。
