But, simply Google "How does science prove that God exists?" to see that there is all kinds of science that proves God exists.
There is no hard science that proves God exists. God is beyond our science.
Stating that science can prove the existence of God is nothing more than extreme conjecture.
God is inside our universe as well as outside. Since He has left us proof in the links I show, etc., He is scientifically proven to exist.
The thing that isn't ever shown is a complete description of Him. In fact, science shows very little about him. But, Whatever or Whoever He is, fits the Thing that put the combinations of scientific facts together in this universe, as my links show.
However, science law and science fact are aspects or parts of science, that have become so overwhelmingly displayable or reproducible, that they are essentially absolutes, scientifically. The absolutes of cause and effect, complex universe, and universal entropy, are so solidly and overwhelmingly in place, that they absolutely exist. The only way they could exist together in a universe like ours is with a God to have brought them about in this universe.
This means that the existence of God is proven, while aspects of His nature, His plans for man, His promises of Heaven and Hell, etc., may not be proven. This is where the believing part takes hold.
God is proven to exist. He is fact. Now we need to believe that what he says is truth... or not, as many people who are known as unbelievers.
