If you can ignore the evidence and give credence to a story which directly contradicts that evidence and must be accepted on faith then you are not a judge of what is rational.
Yes, it may be difficult to “prove” a divine creator created the universe just they way He said He did in the Bible. . . but your side is so full of inconsistencies, incongruities, outright fabrication, nonconformities, and outright bogus theories that I believe my Savior and the literal interpretation of the owner’s manual He gave us.
What evidence?
The only evidence would be transitional species, and a great preponderance of them. None exist.
On the contrary. It takes wisdom to know when rationality alone is sufficient, and when it is not.
