“It’s humbling to realise that the developmental gulf between a miniscule ant colony and our modern human civilisation is only a tiny fraction of the distance between a Type 0 and a Type III civilisation – a factor of 100 billion billion, in fact. Yet we have such a highly regarded view of ourselves, we believe a Type III civilisation would find us irresistible and would rush to make contact with us. The truth is, however, they may be as interested in communicating with humans as we are keen to communicate with ants” (Michio Kaku, “Star Makers”, Cosmos, February 2006).
In the article there is a similar quote – and perhaps a more memorable one – from Carl Sagan: “What does it mean for a civilisation to be a million years old? We have had radio telescopes and spaceships for a few decades; our technical civilisation is a few hundred years old … an advanced civilisation millions of years old is as much beyond us as we are beyond a bushbaby or a macaque.”
