I believe in a creator/ higher power or energy which, hey, our feeble minds just cannot comprehend.
However I also believe he created this planet 4.6 billion years ago.
It's reasonable to believe in a creator, and at the same time accept the things that science has discovered. 400 years ago, we thought the Earth was the center of the universe. 400 years from now, we'll probably know a great deal more about the earth's origin. Was it created in 7 days, just 4000 years ago, and did man walk with dinosaurs? No, we have science which disproves that. however, we're just simple beings and the science behind it all is so complex - to believe we 'have figured it out' is beyond arrogant - it's ignorant.
