I can't see how you can consider this line of thought irrational. These observations certainly lead to questions about the basis of our existance, which may or may not lead peole to believe in a creative intelligence, but the conclusion that Flew comes to certainly appears rational.
Observations leading to questions are one thing, baseless conclusions are another. But what's interesting in relation to Flew is that this is old stuff. He could have (indeed must have) considered these points long before he reached the age of 80. I considered them decades ago.
So think about it. What changed? Has he grown more brain cells as he got older, with which to consider these points? Or maybe.....not.
