#24 - Are We Alone? An Astrobiologist Answers - Graham Lau

Written By Stephen Cowan

In this episode, I sit down with Graham “The Cosmobiologist” Lau — astrobiologist, science communicator, and Director of Communications at the Blue Marble Space Institute of Science. Graham has spent his career exploring some of humanity’s biggest questions:

- How did life begin on Earth?

- Could life exist on Mars, Europa, or distant exoplanets?

- What would it mean to discover alien intelligence?

- And what are our moral responsibilities as we develop AI and explore space?

We cover everything from the Fermi Paradox and the search for biosignatures on exoplanets, to ancient civilizations, UFOs, psychedelics, and the meaning of human purpose in the cosmos.

Graham also hosts NASA’s “Ask an Astrobiologist” show and is a passionate advocate for long-term thinking, storytelling, and connecting humanity’s future to the stars.

If you’ve ever wondered “Are we alone?” or what role humans might play in protecting and spreading life in the universe, this conversation will expand your mind.
