What do you guys think of UFO's?

If you are prepared to make a claim, then yes it is.

What claim did i make against a specific scientific theory, law, etc, that places the burden of proof on me?

As I have said, Experimentation is the only thing that breeds theories. It takes insight to create those experiments, but little is left to the imagination at that point.

Theory comes before experimentation. The reason why anyone would experiment is to test a theory. Therefore experimentation does not breed theory.

Scientific theories are never unfounded. Gravity, Evolution, and the Big Bang are all theories, and all heavily supported by fact.

We have a set scientific method for a reason, because it works almost universally.

Following from fact doesn't necessarily make them supported by fact or true. After all, you wouldn't require things like the scientific method if they were never unfounded. Yet, even if experimentation allowed for shaping a theory to follow from more facts, in the end it is still an interpretation of evidence. Evidence can only support itself; it can only declare its own existence and nothing further. Theories merely expound on evidence, never vice versa.
