One cannot speak and listen at the same time with few exceptions. The human baby’s brain remains in theta, the first 7 years of life and so they can listen and learn even when they are talking. As we age the cognitive ability and progresses change, therefore a teenager never seems to be listening, because they are thinking. Once this child could pick up a curse word in the car while watching a video. The teen cannot seem to retain things that you write backwards on their foreheads. Therefore. You cannot talk and listen at the same time. If you want to hear the voice of God, you must stop talking (thinking) for minute. This, I believe has been the stumbling block of science.
Why has science not been able to prove the existence or nonexistence of God. Number one, science for the most part, is not looking for God. This raises a very interesting question, if science is not looking for God, what is science looking for? Is science looking to disprove Gods existence? And if science is trying to prove God does not exist, for the most part, why has science not been successful? In science, a hypothesis is tested/duplicated to advance to a theory. If the hypothesis cannot be proven but cannot be unproven it can still advance to theory. Why is it that that neither theory/hypothesis cannot be proven or unproven?
It is amazingly interesting to listen to a lecture on quantum mechanics, and quantum wave theory. Most go to extreme lengths to ignore the proverbial elephant in the room, the essence of God. During these lectures some like myself are asking ourselves, where have I heard this before? Oh yes, the bible. The story of the tower of Babylon. God changed the language of the workers so the tower could not be built/completed. Science has so many different diseases looking at different things, and they rarely speak to each other.
The funny thing is the greatest discoveries come from outside the area of study. Einstein was not a physicist, he was a mathematician, the Wright brothers were bicycle mechanics. Point is science can learn something from itself. Look for everything to discover anything.
