Big Pawn: <SugarDom: God does not exist because he can't be seen, heard or observed.?>Nice to see you here <sugardom>, hope all is well.
Yes, some atheists will try that one, but not too many because it's easy to counter.
First we should ask the atheist if he is really going to argue that absence of evidence is evidence of absence.
Of course no one will admit to making this claim.
Also, we should ask what kind of evidence one would expect to find in searching for God. As the creator of the universe we know that God is immaterial, spaceless and timeless.
Back to non observable things:
The natural laws that govern the universe are not observable. We can see the effects of the laws of the universe but we can't actually observe them directly.
We can't observe other minds or consciousnesses. All we can observe is our own consciousness.
We can't observe time, only aging.
We can't observe galaxies that are beyond our current reach.
We can't observe the past but we know it exists when we observe pictures, hear stories etc...
We can't observe some random person across the world but he exists.
Neither can macro evolution be observed, seen or heard.
Another question is raised: is the scientific method the only source of truth? If so, we should point out that the very statement "only those things that can be verified by observation and science" is in itself unscientific! So why should we believe that statement?
But really there is nothing but evidence for God's existence.
1. The fact that something exists instead of just nothing at all.
2. Atheist scientists themselves used to claim the universe was eternal and always existed. Now they say it began to exist at some time in the past, 14 billion years ago. Indeed there was a beginning as the good book says. "In the beginning".
3. The fine tuning of the universe for life is another good argument. That is, the initial conditions at the moment of the singularity. including the laws of the universe, came "pre packaged" as part of the initial conditions of the universe. This is before any cosmic evolution. We are talking about the constants and quantities including the rate of entropy from the absolute beginning. This is evidence of intelligent design.
The moral argument shows us that if you believe moral values exist objectively, you should believe theism is true.
The argument from intentional states is an argument for theism. It basically shows that material can never be "about" something else. Yet, we can think about other things; people, rocks, planets, hurricanes, bananas etc... There must be something more than material in us.
The historic account of Jesus' death, burial and resurrection is evidence for theism.
There are more arguments for theism.
So there are reasons to believe the proposition "God exists" is true.
But there are no reasons to believe that the proposition "God does not exist" is true.
