Well, I believe in biological evolution. But I think more people (including myself) would be more open-minded to the 'intelligent design' idea if it were presented like you just did, i.e. thoughful and concise, with supporting arguments. Sadly, a lot of people use the "itz in da bible so itz reel!!!1" as their first and last supporting argument. That wasn't a jab at religious people, but rather people who use religion to replace all levels of common sense and critical thinking. I think a balance can and should exist.

I'm just curious, but where do you get the low probability variable? Due to the sheer size of the universe (it being limitless and all), I would think that the probability of life developing somewhere would be relatively high.
