Their search isn't even so great any more. They tend to forcefully switch the user input to some generic terms. More than often duckduckgo produces better results for me. I started feeling comfortable using duckduckgo instead of google.
You are just ignorant, Google search is 57% of their total revenue, remaining advertisement is just 19%, people really overestimate how much Google ad network is worth when its just 9.2% of their revenue and YouTube is just 10%. In fact if you remove search Google makes more money from selling subscriptions and services than they do from ads, so they would no longer be an ad company!
Facebook makes much more money than 19% of Google.
Edit: And I wonder why I got downvoted for being right, many here just blindly believe that Google gets their money from ads on third party sites when most of it comes from search.
But I guess your second post is right, it isn't close, Facebook would be much bigger.

That money is a part of Googles revenue, so there isn't as much there as you might think. Maybe you mean there is quantity there but advertisers doesn't pay as much for it as they would for Facebook or Google search ads, then yeah that is possible, but normally in a market segment you count big players by revenue and not numbers sold.
