Who created the oxygen? There are many more elements in air that feed us other then just oxygen, oxygen is only one of many cosmic gasses in air that we can identify. Who created the rain forest? Who designed and blueprinted the seeds that were engineered to grow into giant trees with specific fruits? Who created all the birds and all the plants and trees and fruits and animals that populate the rainforest? Who created the earth to spin on its axis around the sun? Who designed our solar system? Who created the galaxies and the stars and the planets? Is the perfect design and system of the earth and nature all just a big jumbled up jigsaw puzzle that happened to "magically" all perfectly fall in place on its own? Or is there a higher order, a higher intelligence guiding and directing everything?
I hope mh answers you as there is much all inquiring minds want to know.
