  1. Absolutely the stupidest thing I’ve ever heard,

    there is so much evidence here on earth that we don’t want to take in that we are not alone!

  2. This is a pretty bad argument. He’s basically saying “because of math, if i change the numbers in the equation it says we are alone.”

    This guy has a great YouTube channel called coolworlds. Genuinely one of my favorite channels

  4. One question that I hope will be answered in my life time.

    How common is the most basic forms of life? I’ve heard arguments that its everywhere there’s liquid water, possibly even places without liquid water.

    But then others have argued that abiogenesis is essentially nearly impossible, and that’s the great filter that prevents there being intelligent life throughout the universe.

    So far I feel we’ve only really ever looked on Earth, we’ve barely done any looking on the Moon or Mars, and I’m not optimistic about the moon or mars.

    Once we look at Ganymede, Europa, Enceladus. I’ll feel a lot more confident in just how common the most basic forms of life are.

  5. I appreciate trying to ground people and saying “listen, we don’t have enough data here to really draw conclusions.” I DO THINK life is out there, but just because I think something is the way it is doesn’t mean I came to that opinion through facts. And we just don’t have enough facts.

  6. As much as we like to think we’re special, we’re not. There’s countless life out there and the conditions to create it are unlikely unique to our planet.

    Never mind that consciousness doesn’t need to be carbon based like us. It could take many different forms.
