If God did not exist, how does one explain how thanks to the perfectly positioned Moon the Earth is tilted just slightly enough to give us the four seasons? How about the Coriolis effect which allows for rest and night/day? And also how this effect allows for the water cycle in order to keep the land watered and humans can grow food? How about the Moon and how it affects the oceanic tides? How about not having the moon and seeing our days shrink down to about 8 hours instead of 24? How about the moon providing just enough light for us to see at night?How about gravity and keeping us on the ground? How about the Earth being perfectly positioned away from the Sun so that we don't either burn up or freeze to death? How about our bodies and how they are perfectly controlled by the brain? Our circulatory, vascular, and organ systems? How is it that all of these things are fully automatic without us having to do anything? How about the amazing way the kidney's function in filtering the impurities from our blood? There are many more things that point to someone having designed it and created it.
With all due respect, everything points to an intelligent creator.
