"What If We Have Completely Misunderstood Our Place in the Universe ? A Harvard astronomer has a provocative hunch about what happened after the Big Bang. Our universe is about 13 billion years old, and for roughly 3.5 billion of those years, life has been wriggling all over our planet. But what was going on in the universe before that time ? It's possible that there was a period shortly after the Big Bang when the entire universe was teeming with life. Harvard astronomer Avi Loeb calls this period the 'habitable epoch,' and he believes that its existence changes how humans should understand our place in the cosmos. The full article is here"

I do not know about the very early universe, but our galaxy started with the Galactic Bulge, which went through a period of star formation about 11 billion years ago, including the formation of high-metallicity stars (and, thus, presumably, planetary systems like ours).
Any civilizations formed in the bulge would presumably be at least 6 billion years old now, spread throughout the galaxy, and be used to conversations taking thousands of years to get anywhere. They may come calling in 5000 or 10,000 years or so.
