he argues that humanity’s religious instinct is what sets us apart from other animals – and it carries powerful evolutionary benefits.
Voltaire raised the question. "if God did not exist, humans would have to invent God " or Is something real because it is true or true because it is real?
Most of us would say that something is true if it is real, but there are somethings that challenge this view. For instance is 2 + 2 = 4 because it is real, or because it is true? I would say that is real because it is true although the reality of mathematics is different from the reality of a thing.
Now probably because so much science is being done through math and not in the lab these days the line between truth and reality seems to be getting very thin. The math supporting the multiverse appears to be true, but there is no hard evidence that it is real.
Since atheists deny the existence of God the necessary Being Who gives true and reality to Existence many atheists have decided a utilitarian approach to Truth and Reality, in other words practical truth is reality. If something works it is true and real.
The problem with this happens when they find that the Christian faith is practical, it is both true and real. Does that mean they change their mind about the reality of God. Sadly not because their assumption is that God is not real or true and they are not willing to challenge that assumption.
In a sense it is the flip side of fundamentalism. They believe that the Bible is the absolute Word of God. When they find out that it is not, do they stop believing in God or change their belief in how God works, because God is not dependent on our theology?
I do not know of atheists have that flexibility.
If God did not exist, humans would have to invent Him." God does exist so we do not have to invent God.
