The following is a conversation with Sarah Walker and Lee Cronin.

They have each been on this podcast once before individually, and now, for their second time,

they're here together. Sarah is an astrobiologist and theoretical physicist.

Lee is a chemist, and, if I may say so, the real life manifestation of Rick from Rick and Morty.

They both are interested in how life originates and develops both life here on Earth and alien life,

including intelligent alien civilizations out there in the cosmos.

They are colleagues and friends who love to explore, disagree, and debate nuanced points about

alien life, and so we're calling this an alien debate. Very few questions to me are as fascinating

as what do aliens look like? How do we recognize them? How do we talk to them? And how do we make

sense of life here on Earth in the context of all possible life forms that are out there?

Treating these questions with a seriousness and rigor they deserve,

so that I hope to do with this conversation and future ones like it.

Our world is shrouded in mystery. We must first be humble to acknowledge this,

and then be bold and diving in and trying to figure things out anyway.

And now, a quick few second mention of each sponsor. Check them out in the description as the

best way to support this podcast. We got uncrews for adventure, linoed for cloud computing,

expresscpm for privacy, roca for style, and athletic greens for performance.

She's wise and my friends. And now, onto the full ad reads, as always, no ads in the middle.

I tried to make this interesting, but if you skipped them, please still check out the sponsors.

I enjoy their stuff. Maybe you will too.

This show is brought to you by a new sponsor called uncrews adventures.

Small ship cruises sailing to Alaska, Mexico, Costa Rica, and Hawaii.
