For accepting evolution? Hmm...
There's a very real sense in which it never occured to me not to. My parents both hold Zoology PhDs, so I "accepted" evolution since I was old enough to understand what the words meant. I certainly accepted it when about 6 or 7.
As time as gone on, of course, I've found out more about it and learnt about the evidence that supports it. And none of that has ever given me a reason to reject it.
