Evolution *is* the only scientific game in town. Besides which, it being 'only a theory' is meaningless. Gravity is 'only a theory'. That germs cause illness is 'only a theory'. The theory which allowed us to build nuclear weapons is 'only a theory'. The theory which allows us to make transisotrs for your computer is 'only a theory'. Something being a theory doesn't mean it's ill established at all.
Also its an observable theory, why do you think we need to make a new flu shot strain every year. Yep you guessed it. Evolution
Or my favorite concern, MRSA. People will often want to distinguish between 'micro and macro' evolution and say that while micro evolution can be true macro is not, but I find that distinguish to be arbitrary. Physically, macro-evolution is a bunch of micro-evolutionary steps over time. If one is a fact then that the other happens is all but certain.
Haha, yes I was worried someone might bring out the "micro" argument. I couldnt have put it better than you did on how macro is just lots of micro over time

Einstein,
I basically agree with you, too, with the little exception that I disagree in that the whole of what this theory describes was observable - is it this what you were trying to convey, or did you rather mean that parts of this theory are observable?
Just some evolutions are, that's it.
Well macro evolution isn't observable like micro is within one year. But DNA shows an intricate tree of life over thousands of years, Also fossils show transitional species over time linking common ancestors, so in that way its observable.
