Secular viewpoints
God exists only in the imagination
It could be argued that God exists only in the imagination. If God exists only in the imagination, He does not exist in reality and therefore cannot be known. However, the entire external world could also exist only in the imagination as well.
Under this skeptical viewpoint, it is possible that we are all brains in a vat and that our sense perceptions of the external world are generated from electrical stimulations to our brains in vats. No one can prove that the external world exists in reality outside of our sense perception. So it is possible that the external world does not exist in reality independently of our sense perception. Therefore taking the same line of reasoning the external world cannot be known either.
If it is possible that everything we perceive could be in our imagination, God would still be in our imagination even if we could perceive Him. That we cannot perceive Him does not, therefore, prove that He does not exist any more than perceiving the external world proves that it exists, because it is possible that the external world exists only in our imagination and does not exist in reality outside of our sense perception.
Scientific evidence proves that God does not exist
It could be argued that scientific evidence such as the “Big Bang Theory,” the theory of evolution and the Higgs Boson “God particle” prove that God does not exist and therefore cannot be known.
“Big Bang Theory”
The “Big Bang Theory” or the accelerating inflationary big bang model is used in the cosmological causal argument for the existence of God to prove the premise that the universe began to exist.
While the “Big Bang Theory” explains the creation of the universe from a pre-existing singularity, but it does not account for the creation of the singularity.
Theory of evolution
The theory of evolution suggests that living organisms came from other pre-existing living organisms and are related by descent from common ancestors with the variations in living organisms due to changes in successive generations.
So it is said
- that mammals including human beings descended from shrew-like creatures that lived more than 150 million years ago;
- that mammals, birds, reptiles, amphibians, and fishes descended from aquatic worms that lived 600 million years ago;
- that all plants and animals descended from bacteria-like microorganisms that lived more than 3 billion years ago.
