I beg to differ, lots of people have defined the term God.
Ok, so perhaps that should have read, no has
as yet successfully defined the meaning of the term God or the noun, in as much as a definition of the word and its meaning is as varied and open to interpretation as the people who are doing the defining of it.
If one accepts or wishes to investigate the theory that "God created man in his own image", the logically then if one wants to understand "God" better, there are two avenues of study:
Study God
Study Man
since God isn't readily available to interview and theres a wealth of data regarding "Man" i wussed out and took the route thats simpler and more easy to quantify in experimental and evidential terms. Helpfully this can also be used when investigating the question "did man create God"
and why is it that evolution is problematic from a Christian or any other POV? there are many continuums in life. Evolution is just one.
I was once asked (by an RE teacher) can one be a scientist and a christian.
"yes" i replied
"but how? the theories are contradictory."
science deals with the question of "how" religion onthe other hand is asking the question "why"
Thus they can co exist, and one can hold both religious and scientific beliefs.
