Ahh... this is a classic topic.
I am a christian.
however i Believe in intelligent design (God created a life form and then allowed evolution to occur).
I may be wrong, i know but lemme explain my argument:
In the bible, God makes himself know to early man (Abraham). abraham wouldn't be able to comprehend a single-celled life-form being changed through adaptation and natural selection into what is now every bit of life on the planet.
Also, in the bible, god says he made all life, he doesn't specify how he did it.
he also said in "days," a day, as we know it, is 24 hours, but through-out space, "days" are different lengths, so in another dimension (i likely place that an omniscent ruler of the universe would inhabit) "days" might refer to "millions of years"
back to abraham, early man. he wouldn't comprehend "millions of years" cuz he probably didn't make it to 50 years old. i also don't think he would understand mass extenctions, or even care, for that matter, he has a family to feed.
