Page Rank is not rocket science. Sooner or latter someone else would have come to the same conclusion (using incoming links to asses popularity).
I don't doubt that Larry Page is a talented man, but he was in the good place in the good moment. Now Google is in a dominant position and there's no place for any competition, but if Google never existed, we would have some other company doing similar things as Google. Maybe they would have appeared one year later.

Indeed, at the same time as Larry Page was thinking about PageRank, Li Yanhong created and patented RankDex (a very similar page ranking algorithm) over in New Jersey - and built Baidu out of it.
Many scientific discoveries seem simple after the fact, like the Einsten's E=mc2, yet somehow it took one of the greatest minds in history of mankind to come up with it.
