We couldn't communicate with the most advanced primates from a million years ago. A civilization a million years past ours would be unlikely to want to talk to us. The average star in our galaxy is a billion years older than our sun.
Based on what? Just because a civilization is extremely sophisticated doesn't mean we have nothing to offer.
We still study primates and ants. Hell, we even desire that we could communicate with chimps and dolphins.
Communication is impossible with primates and ants simply because they lack the hardware to engage in abstract communication.
We as a species are very hostile towards all forms of life on earth. Some of us are scientists and open to communication and peaceful existence. Some of us are locusts, everything is devoured for personal gain. Our track record for meeting other species and other human cultures is such that were the roles reversed, meeting a human traveller from another star system would better be met with armed resistance.
