As others have observed there are only three wires coming into the house and both ground and nuetral go to the same bus in the breaker box. The reason for two wires going to the same place is redundancy to reduce the risk of a wiring failure preventing a proper ground and possibly leading to someone getting hurt. As a society we got by without it for many years but decided about 15 years ago to improve safety by doubling up.
If you look closely at the panel photo above, there are actually 4 wires coming in to the box. The two hots and neutral come in through the center conduit, and the safety ground from the outside ground post comes in at the upper left.
