There were no witnesses.

There is no way in the world Scott Peterson could have known on Chritmas Eve when the police arrived at his house that nobody saw him at that marina.

He had no choice but to say he was there.

Right! And in fact we now hear of some guy who DID claim to see Scott there that day. There were so few people there, he noticed, and Scott probably noticed HIM, too. So he probably knew someone saw him there.
