I would look at the scientific evidence for evolution this way:
There are two types of evidence that can support it:
1)Historical
2)Experimental
Historical is to be preffered because no matter how many times you experiment on something and it comes out a certain way, it is--to use a philosophical term--an inductive argument, meaning that there is still assumption involved, you assume that it will come out the same the next time even though it might not. Really, IMO, experiments can "prove" nothing, holding to the strict sense of the word. They may be enough to convince some people, but you are still believing in something, it is not proven. In truth, it is a belief system also.
Historical evidence is the way to go IMO, and there is no convincing facts for evolution (in the crossing species form) there either.
In short, evolution has no facts. Therefore, your arguments about teaching facts in schools is void. Evolution should be taught in schools, but not as fact.
One thought that still occupies me that no one had a reply to (most likely b/c there is no answer): How did matter evolve? There is no scientific basis to say that something came from nothing, which is highly ironic b/c evolution claims to be a strictly scientific theory.
