As a practicing scientist, I have to point out that there is a lower level than hypothesis that many non-science people wrongly claim to be an actual hypothesis. This concept is called an 'idea' (there may be a philosophical term that may accurately describe this better, but I will use the term 'idea' for simplicity's sake). A hypothesis is an idea that developed to the point that allows a scientist to test this idea with the theoretical framework of the scientific discipline he/she is practicing in. A simple idea is just something someone thought-up, and is not yet testable because an experiment or derivation (if you are a theorist) has not been devised to test it. Or in many cases, it never makes it to that point. It just kind of stays an idea and never matures.

Or in the case of Creationism, it is just a shitty idea that refuses to die. It cannot be tested, so a viable hypothesis can never be developed. It is intellectual junk.
