Boxing Tally nailed it. Did you know that the big-bang and evolution are accepted as fact by, the Pope and the Catholic church of Rome, the United Methodist church, the Presbyterian church, the Anglican church of England, the Muslim sect of Sunni and Shia (the two largest of Islam) the Dali Lama, the conference of American Rabbis, and 95% of the educated industrialized world?
Scientists who believe in both are called Creation Scientists so something lime that. I am the same and believe its just a matter of accepting God as all powerful rather than limiting Him by saying He could only have done it instantaneously. God made EVERYTHING including those processes we call 'evolution'.
This is my position. It is typically a variant form of reasoned faith. The deists, intelligent design and liberal theologians might fit within this camp, but there is not one group that fits all. A recent survey of people in the United States shows 60 percent of Christians believe in some form of evolution, while 40 percent believe exclusively in creationism. I suggest the majority have the floor, while the minority may continue to ask hard questions, questions that generate research. I know scientific atheists who are quite uncomfortable with me as a theist being a supporter of evolution; they are skeptical of everything I say. Yet when I ask them for a mechanism for a haploid evolutionary shift, say from prokaryotes to eukaryotes, or invite a dialogue on how 60 percent of the species appeared in about 12 million years in the Cambrian Explosion, I am met with silence. We have our issues in evolution, issues that generate research because we dont know everything; we don't want to admit we don't, as it encourages the Luddites with the wrenches.
There's no problem, the Big Bang happened,god caused it. Maybe that's the way he chose to create the world. All scientific theory's are possible, if you put god into the equation, after all god created science.
