A solar creation myth from Japan contains a reference to a floating cloud in the midst of infinite space, before matter had taken any other form. This also nicely describes the original nebula from which scientists say the solar system was evolved. The legend says that when there was no heaven, earth, sun, or moon, there was only the Invisible Lord of the Middle Heaven existing in an infinite space. With him there were two other gods. Between them, they created a floating cloud in the midst of which was a liquid formless and lifeless mass from which the earth was evolved.
