Based on the type of light it emits we can gauge how much of its hydrogen has been converted into helium, and thus tell how long it's been around burning that hydrogen. Assuming the planet followed what we understand as normal planetary formation, it would have formed from debris around the star a few million years after the star itself formed.
Well then I suppose that could put some evidence twords the statement that life on this planet most likely has not had time to evolve as much as humans. I am however still open to thinking that there is a possibility that the planet was formed before the star.

As for talking about brains, it is possible that this slight evolution in the brain has happened on other creatures far away from us. This would then show us other life that has a far more advanced brain then humans,but it still dose not define their intelligence.
