Well then - I guess you'd really hate physics then, a field that reduces everything you see around you to a series of equations with a tad of randomness thrown in for good measure.
Now then - if you don't believe humans obey the law of physics - well then - that's your problem.
To put it another way, it's like trying to fix a watch with a shotgun. And as long as you would like to keep the watch, I'd say save the shotgun for other uses.
Pure determinism is fun to play with, and you can believe that it is the ultimate answer, but it has no real use here and now.
This is separate to my main point, but I like this quote from E. F. Schumacher: "Relativism and positivism, of course, are purely metaphysical doctrines with the peculiar and ironical distinction that they deny the validity of all metaphysics. including themselves."
You took down a straw man.
"Finally, physics eliminates the case for free will. So yes - you do what you do because you were set up to do it."
Also, for the purposes of my argument randomness doesn't really matter, anyway. It's whether you exclude free will or not.
I'm not a Christian, but I can easily see how someone could be a Christian while not accepting the fundamentalist outlook (i.e. that the world is only 6,000 years old, we're not descended from other species, etc.). Those "other" Christians believe in God, but don't accept the literal interpretation of the Old Testament.
To argue that all Christians are fundamentalists would be like arguing the all Muslims want to fly airplanes into buildings. As a viewpoint, it lacks evidence.
Even Einstein held something resembling a religious outlook -- but his supreme being couldn't be bothered to deal with us lowly insects:
“I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with fates and actions of human beings.”
Also, remember that, until the end of the 19th century, there was no plausible way for the sun to have been in existence for more than a few million years (in that pre-relativistic era, the sun's energy was thought to arise only from gravitational contraction), which wasn't enough time to support Darwin's timetable. So at that time, even scientists couldn't explain how complex species arose.

That's my outlook also, but I can see how religious people might possess different views on the literalness of scripture.
