I understand that the genisis block was created by Satoshi but what about the 2nd block? if Satoshi never spent any of the first coins what was the inputs for the 2nd block 
I thought we where hashing transaction data but the first 10 blocks where not involved in any transactions.
in fact what was the first block to be spent?

Transactions are only verified, they aren't required to hash a block. It's entirely possible to mine blocks without any transactions in them.
if you are right - it looks like if we just imagined,drew ( somewhere in database on a server) some symbols and called them 'coins' with fixed amount of them,for example 21M , and said that these symbols could cost smth and began trade them
or for example we could take 1 paypal usd or 1 libertyreserve usd (no matter what exactly, even pixel or some bits or smth else digital) and agreed they could cost 0.1 or 10 or 100 real USD etc and that there couldn't be more then 21M of them
In comparison with Bitcoin, Bitcoin network only guarantee protection from printing new coins by somebody except bitcoin users , final amount 21M and absence of central authority issues new money
and the question is where do all the blocks, coins take value from ?
