The Milky way is only 13.6 billion years old while the earth is only 4.5 billion years old.
Saying there isn't any other life in older parts of the universe is insane.
The Milky Way isn't much older than the known universe (13.8 billion years). Our galaxy is properly old even if our particular solar system isn't.
NB. @Zarjazz' hypothesis is a bit misleading, carbon and oxygen atoms were being created "only" 400m years after the Big Bang because the first stars went pop relatively quickly; there's still a very long period of time available for solar systems and potentially life, to live and die.
