Neil deGrasse Tyson, like Michio Kaku, is a pop scientist who manages to find the balance between entertaining and actually informative that seems to elude most documentaries. In this short clip from a much longer talk, he discusses three main things: our chemical composition as it correlates to the universe, why we should look at other planets in the galaxy (and especially in our solar system), and the weird possibilities that aliens represent.
Based on a couple of ideas he throws out, we might either be descendants of Martians, something he discusses rationally and plausibly, or have a 1% DNA difference from the first aliens we meet in the way that chimps have a 1% DNA difference from us.
Either way, we're not that special.
If you’d like to theorize about our potential extra-terrestrial origins or any other part of Neil deGrasse Tyson's ideas, please leave a comment and get the debate rolling!
