In my way of thinking, all theory is conjecture, but not all conjecture is theory. Do we agree?
Why do creationists always insist on changing the meanings of words? Why can't you just use them to mean what everyone else does? RWP is right, a scientific conjecture is far weaker than a scientific theory.
No.
Conjecture: inference based on inconclusive or incomplete evidence; guesswork.
Theory: Systematically organized knowledge applicable in a relatively wide variety of circumstances; especially, a system of assumptions, accepted principles, and rules of procedure devised to analyze predict, or otherwise explain the nature or behavior of a specified set of phenomena
