When it says in the last date 2009-01-09 what does that mean?
When syncing the blockchain you will start at the very first block (the genesis block) and work towards the last known block sequentially. You're debug.log is just referring to a block it received from 2009. The progress indicator being at 0.000000 also gives you a hint this is from very early on in the syncing progress. When you are fully synced the progress indicator should be at 1.000000
In other words: this will happen to anyone fully syncing from scratch. This has nothing to do with your wallet and the possibility it could contain coins from very early on.
