Because five hands with two fingers would be asymmetrical.

It's just how we evolved.

how else would I ((HIGHFIVE))) You:)

I don,t no but try getting along with out them

Evolution. . Five fingers are common in many (if not most) vertebrates. http://upload.wikimedia.org/wikibooks/en/1/1d/Anatomy_and_physiology_of_animals_Various_vertebrate_limbs.jpg . Maybe You'll find the answer here: http://books.google.pl/books?id=P1LkOL1CijEC&pg=PA75&lpg=PA75&dq=why+vertebrates+five+fingers&source=bl&ots=SbEwqQRJl0&sig=ydUN-aU9im4a0C549b4EA54-d8Y&hl=pl&ei=qzfISsDqMYXJ-Qal4Zk_&sa=X&oi=book_result&ct=result&resnum=6#v=onepage&q=why%20vertebrates%20five%20fingers&f=false ============================= As for 2 hands. Because we had four limbs (tetrapods) and then stood up. That leaves 2 legs and 2 arms. Why four limbs? Also evolution. And the answer might also be in the above book. . I'm too lazy to read it.

In my opinion this question can be answered through the understanding of nature, especially human nature in relation with some sort of logical explanation. I propose linking this question with : First : The Bible, the Word of God. Second : Prime Number, one of the subject of Number Theory, one of the branch of Mathematics. First of all, I will explain the answer from the Bible. Now, Let's do a simple mathematics; 2 times 5 equal 10. Where do you find number 10 in the Bible? The answer is from the Old Testament book; Exodus 20:1-26 The Ten Commandments, 10 SIGNIFIES that God give human 10 commandments; MATCH, not more or not less, 10 fingers in which God had created human. The first 1-5 commandments goes to God, the second 6-10 commandments goes to human. The 5th command goes to God because we cannot choose our parents. So as simple as that, we are given 10 fingers by God, to be counted, to do work, to play guitar, to glorify God, to make human REALIZE that there is 10 basic principles to LIVE in this world. Second, I will explain the answer from the Theory of Prime Number : Prime Number is a number which only have 2 factors, 1 and the prime itself. For example; 7 is a prime number, the factors are 1 and 7. But 6 is not a prime number because it can be factored into 1, 2, 3, and 6. Prime Number can be classified into 3 groups : A.) The first group is based on Divisibility, the Remainder if we divide Prime Number by 9 (P = R mod 9) : - P = 1 mod 9 (examples : 19, 37, 73, 109, etc.) - P = 2 mod 9 (examples : 2, 11, 29, 47, 83, 101, etc.) - P = 4 mod 9 (examples : 13, 31, 67, 103, etc.) - P = 5 mod 9 (examples : 5, 23, 41, 59, 113, etc.) - P = 7 mod 9 (examples : 7, 43, 61, 79, 97, etc.) - P = 8 mod 9 (examples : 17, 53, 71, 89, 107, etc.) B.) The second group is based on the Least Significant Digit of Prime Number (the unit) : - LSD 1 (examples : 11, 31, 41, 61, 71, 101, etc.) - LSD 3 (examples : 3, 13, 23, 43, 53, 73, 83, 103, etc.) - LSD 7 (examples : 7, 17, 37, 47, 67, 97, 107, etc.) - LSD 9 (examples : 19, 29, 59, 79, 89, 109, etc.) C.) The third group is based on Uniqueness (Only reside in one groups at once) : 2 3 5 These Prime Number (2, 3 and 5) are Unique because they only belong to one groups at once, That's why we human have 2 hands, 5 fingers and 3 brains !!! I said that 3 brains, Why? Because the Left Brain cooperated with the Right Brain created the Third Brain, that is the reality, the working principle of our Brains. Moreover I said to you 3 hands, Why? Imagine someone playing guitar, the Left Hand cooperated with the Right Hand created the Third Hand, that is the reality, the working principle of our Hands.
