"Just a theory" doesn't cut it. I suspect your understanding of the meaning of the word, "theory" is a bit weak. Let's start with a real
definition of the word:
the·o·ry (the'?-re, thîr'e)
n., pl. the·o·ries.
- A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.
- The branch of a science or art consisting of its explanatory statements, accepted principles, and methods of analysis, as opposed to practice: a fine musician who had never studied theory.
- A set of theorems that constitute a systematic view of a branch of mathematics.
- Abstract reasoning; speculation: a decision based on experience rather than theory.
- A belief or principle that guides action or assists comprehension or judgment: staked out the house on the theory that criminals usually return to the scene of the crime.
- An assumption based on limited information or knowledge; a conjecture.
The last definition appears to be what you have in mind and is common in less demanding conversation, but in science, a
theory is only acceptable
if it has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena. Furthermore, it takes only
one exception to disprove a theory.
Creationism, "creation science" and other so-called "theories" of divine causation simply do not meet the criteria for a
valid theory. They can't be tested, and they can't be used to describe or to make repeated, accurate predictions about natural phenomena in any meaningful way.
Unless you can disprove evolution, or at least provide an alternative that can be tested in the real world, it's the only explanation that fits the criteria to be accepted as a scientifically valid theory.
