I'm not sure if you're being serious or silly, to be honest! I'll assume you were being serious, and if you were being silly, joke's on me I guess :)

The process of proposing a hypothesis, running experiments and collecting data, and using that to form a conclusion which helps modify your hypothesis, was taught to me from a very young age, in elementary school, high school, college, and extracurricular learning, as "the scientific method".

You appear to be upset that the definition of hypothesis says that it can be 'modified', but science doesn't claim to know the answer. Religion is something that does claim to know the answer. Science on the other hand recognizes that we only ever have part of it. We're ever trying to get closer and closer to a full understanding, always advancing our hypothesis, and testing it against what we find in the universe around us.
