You know, Dave, sometimes it's just better to keep your mouth shut when you are ill equipped to enter a conversation. Do you even know what a hypothesis is? Sorry, rhetorical question as you obviously have no idea. The definition is a proposition made on the basis of reasoning without any assumption of its truth.
Since you won't understand that, I'll give you an easy example like they teach every 5th grader that has ever participated in a science fair, a hypothesis is basically "if I do this, then I believe this will happen." At the point of the hypothesis that are no facts to determine whether it's true or not, that's what the science is for.
My hypothesis is "if Marshall and wvu had played a football game in 1999, then Marshall would have won." Since we can't go back in time and play that game, you have to then collect data and analyze that data to draw conclusions as to the likelihood of the hypothesis being correct. Like many things with science, you can never be 100% certain of the outcome, but you can develop a level of certainty through the proper collection and analysis of the data. For example, there was no way for NASA to know for sure that they could launch a rocket and successfully put people on the moon, but their extensive analysis indicated that it was highly probable that they could. It didn't become a fact until the lunar lander touched down, several years after the original hypothesis was made.
Now you have the level of understanding concerning a hypothesis that is consistent with a 5th grade education. Congratulations.
