Like I said, doesn't the evidence in the code and in the blockchain show that Bytecoin didn't exist until 2014?
I'm sure it isn't. Premines are pretty obvious things that would stand out and be easily noticeable in both the code and the blockchain. You would see a method such as the following in the code:
int64 static GetBlockValue(int nHeight, int64 nFees)
{
int64 nSubsidy = 100 * COIN; // sets default block reward to 100 coins
if(nHeight == 1) // in other words, if block height is 1...
{
nSubsidy = 1000000 * COIN; // ...then whoever solves that block gets 1 million coins
}
else if(nHeight < 5001) // otherwise if block height is less than 5,000...
{
nSubsidy = 200 * COIN; // ...then whoever solves these blocks gets 200 coins
}
nSubsidy >>= (nHeight / 500000); // block reward halves every 500,000 blocks
return nSubsidy + nFees; // returns the block reward and mining fees to whoever solves the block
}
Even if you don't understand C++, the comments make it pretty straightforward. The above coin would have an initial premine of 1 million coins. It would then have 200 coins per block for the next 4,999 blocks and then revert to the default block reward of 100 coins per block after that. The block reward would halve every 500,000 blocks.
As for the block explorer, well the timestamps certainly match up. Below is the link for block height 1. Note the part which says "2012-07-04 05:00:00":
