Astrophysicist and author Professor Neil DeGrasse Tyson says it would be “inexcusably egocentric” to believe humans are the only life form in the universe. “We are made of the common ingredients in the universe: hydrogen, oxygen, nitrogen, carbon, iron,” he told Sky News Australia host Piers Morgan. “This stuff is everywhere in the universe, life on Earth was opportunistic.” Professor Tyson said on Earth, “life started almost as quickly as it possibly could have” – and there are hundreds of billions of galaxies and solar systems beyond ours and the Milky Way. “To suggest that we are alone in the universe would be inexcusably egocentric driven by some philosophy that is not grounded in observational science,” he said.
