Creationism and Evolution are not mutually exclusive. The ‘7 days’ in the story of creation are just interpretations for longer periods of time. The ancients did not use large numbers like ‘millions’ and ‘billions’ commonly, so they simplified the number to retain the story but not the details.
God and science are also not mutually exclusive. In fact, the more you understand about science, the most clear it becomes that something manipulates that very grains of matter that surround us.
Either way, you will never be able to prove God does not exist. For if there isaGod that created the very fabric of the universe, surely God hasaway to pull the veil over our eyes.
