This is a great documentary, a must watch. Even if you're not interested in the subject, it's still a must watch imo. It's extremely persuasive and a valuable contribution to this topic and part of an ongoing conversation about life outside our solar system and even the status of our own planets health. For anyone new to the topic, it builds a case starting with very credible evidence from the 1940's. So, for people who've been into this for a long time or think they know a lot, it may seem 'we've seen this all before.' But I think it's important to see this documentary for what it is, which is a case to be made for proof of life beyond our planet. And if you're sitting on the fence on the topic, this will help push you off.
