I think it is because the thumb seems to be a distant from the other fingers. It is however part of the fingers and it is actually the first digit of the hand. For more information, check out http://en.wikipedia.org/wiki/Thumb.
I think it the same. But I guess people in the medical community say it ain't. But I found this definition: any of the five jointed parts projecting from the palm of the hand. Sounds to me like your thumb is a finger.

Because they look differently. Thumbs are fingers, though. Medical people DO call them fingers, or at least they have the same medical terminology as fingers. No medical people actually call them fingers and thumbs; not when they are at work, anyway.
people say that the thumb is not a finger because it is shaped differently, different size, and it bends differently. it also does not end in finger like: the index-finger, middle-finger, ring-finger,and the pinkie-finger. i do believe that the thumb is a finger because when you are young and people ask you how many fingers you have, you will say five. Plus if it wasn't a finger: what is it then.
