If you count average is 29, then that means there is a whole bunch of 25 - 35 in the range, all over the world. Typically CS students graduate from undergraduate around 22, 23 years old. Google and FB are very popular in the new graduate community and they needed a lot of fresh blood every year to fill in the gaps. Not every position at Google is going to be exciting. The job description is catchy but the your responsibility and assignment may be dull. A lot of older folks may find dissatisfying and because of their seniority they can find similar pay at other companies. There is also a network effect. Sure, younger folks tend to connect with other young folks.
Like other comments said, one can't prove age discrimination easily. Google has a very rigorous hiring process. One ex-Google said one time the hiring committing sat in a room and rejected all applicants. The recruitment team came in and said those profiles were the committee members themselves when they applied to Google.
