It isn't ambiguous under the commonly accepted scientific facts of the time, in that particular civilization. They believed that they were on a flat earth under a dome that separated the atmosphere from huge amounts of water above (hence the blue color of the sky) and below (hence the oceans). They believed that the dome leaked sometimes, causing rain. They believed that the flat earth leaked too, causing rivers.
