Duke, you're not a big believer in a coherent sentence, are you?
Evidence, theory, guessing.
You're a layman, and when you say you have a hypothesis, you mean conjecture, a quick guess. When a scientists says they have a hypothesis, they mean they spent a few days at the library and were unable to prove themselves wrong, and so formulated a hypothesis.
Science is a guessing game, but our definition of 'guess' is the same as your definition of 'proof'. It's harder to convince a scientist that something is true than it is a layman like yourself. Why, I just bet I could have you convinced through a series of seemingly logical turns that there are only four elements in the universe.
You're the kind of person who would have accused a chemist of witchcraft in the 16th century, or voted to hang Galileo for refusing to believe that the sun was the center of the universe. As for believing in the big bang, I absolutely do, and this is why (assuming you can understand it, which I doubt):
You share 98 percent of your DNA with a chimpanzee. You're more closely related to them than they are to gorillas. You shit, fart, blow snot out of your nose and carry all manner of bacteria in your mouth and on your skin. You don't have any special dignity, you're not a 'child of god'. When you step on a bug, it dies. When you get shot in the head, you die, and you don't come back.
