Observations do not constitute a theory. They can only help to validate or invalidate. One of the major observations required to validate evolution is missing. In addition, so is the mathematical evidence. The statistics are simply against it.
Quite correct. Only evolution is neither observable (in action) or repeatable, hence it can (at best) be only a theory, not science. I guess it always comes down to faith. Either in a Creator, or man's interpretation of what he sees around him (therefore, man himself.)
