Sevan-"Giles Gray, the concept that everything, in all its wonder and complexity, just got here by chance, does not and cannot make rational sense to me. That scripture about every house having a builder really hits home for me, especially when you consider that the natural world and universe is far more complex and awe-inspiring than any house."
Just because an alternative concept doesn't seem to be rational doesn't automatically prove the one you hold dear is anymore rational either. Both could be wrong.
If both concepts have inconsistencies then it would be irrational and illogical to claim you could never be shaken from the one you are most familiar with, just because you've believed it longer.
The only rational approach would be to consider both concepts objectivly. You can't achieve that by holding a bias towards a cherished concept. If that concept proves incorrect then so will be your conclusions. It would also demonstrate a lack of open mindedness.
