Faith is stronger a greater pull than reality at times. But the reality is always there and influences the faith. We were once non-existantant till God called us into being. You have to have faith in the reality and in the hope. There is so much we can distract ourselves with.
There is a message there is one Gospel one way. How we got here as a species is like wondering how the jug of milk got into the refrigerator. It is important to a point. The base part of our faith is that we were created as a race and that each one of us is individually created and did not exist before our conception.
