And if someone defines "God" as "all that is", does an atheist not believe in things that are and the agnostic not know whether or not the things that are, are?
This is good question, since it bring to light the main difference between science and religion. God is a 3-D concept, since the concept of God covers all the bases of known and unknown reality, simultaneously, in time and space. God, as concept, may be nebulous but it has to integrate even opposites, which science leaves separate since this easier.
Science is more 2-D and differential; cause and affect. Like in calculus, Science is good at differentiating reality; slope at a point on a curve, while religion is more about integrating; area under the curve. This makes religion superior, since it is harder to integrate data, than it is to differentiate it. The latter only needs better tools; better telescopes, while the former needs more brain power; seeing data plus evolve theory toward 3-D. The new space telescope has given us picture of galaxies that formed earlier in the universe than was expected based on the current theory. Science is stuck perpetuating obsolete theory since it is easier to see than to synthesize.
Religion went through a stage growth from polytheism to monotheism. Science is still in its own rational polytheism stage. This throw back to polytheism, is connected to specialization and specialty theory that cannot transcend its own specialty niche. What does biology teach us about particle physics, since both are about what science calls hard reality. They cannot, in their current form, tell you anything about each other. One is the goddess of rain and other the god of fire. Religion advanced to one theory; God, that covers all the bases at a conceptual level; God is 3-D. Fire and rain are part of a whole, just like good and evil is part of a single coin. Science can only see one side of that coin, at a time; differential or 2-D.
Science cannot yet differentiate God; have proof or disproof, never mind integrate God with Science. Whereas, religion has concepts like an omni
science God. Religion has an extra, but intuitive fuzzy z-axis beyond cause; x, and affect; y. The z-axis requires one learn to use internal sensory systems when moving around data; mediation, prayer, intuition and faith.
I am able, as a trained scientist, to develop integral theories, by making use of 3-D thinking skills I learned from religion; right brain. I used science to help me differentiate, the brain's firmware and operating system data. I learned integral thinking by seeing how the inner self, placed these parts back in 3-D. I could break it down into parts but could not puts the piece back together; dissociated state of mind. The inner self helped to reorganize and I watched and helped fit it together.
Science is like going into the woods, and losing track of the forest because of the trees; so many firmware expression. It approaches reality based on the specialty data in front of your nose. The theories of Religion are more integral and 3-D and sees the forest from the top of the ridge, and therefore can see all the trees of the forest in terms of patterns and wholeness. However, it cannot see each tree in the same level of detail as science; the religious theory of creation lacks the details of theory of evolution. But science cannot fully see what other specialty areas of science are doing, so it can not design 3-D theory that can cross the boundaries of all specialties. How does the BB theory impact evolution of life leading to the rise of civilization ? This requires integrating physics, with biology and psychology, which are now like three different specialty gods in science, each with its own jargon and ways to worship.
Science has de-evolved over the past century due to too much dependency on casino math and science. As an example, when the weatherman says there is a 50% chance of rain, what does that mean? The god of the oracle has spoken. This casino science approach to weather is very subjective, and can mean what you want it to mean; half the day, half the hours, or we need to call the bookie and place a bet, thereby allowing any bad theory to appear rational. Coffee is good today but bad tomorrow based on who spins the wheel of fortune; statistical experience and whims of the gods.
The consensus of science is now based on politics and fads and not reason. Why did science allow this subjective dumb down? The answer is politics has the money for the gambling. Science needs to sober up; go to gamblers anonymous and return to 2-D science, instead of stay regressed at 1.5-D science; not fully rational but with emotional appeal, usually fear. They're a casino science bogeymen everywhere. Everything has finite odds own any given day. This may be the hottest season on record or the sun is acting funny so be on guard. This is lower than religion. Science needs to right the ship.
