Thanks for fulfilling my lifelong dream of rolling into a ball to pretend to be a uranium atom!

The fact that basic single celled life developed almost as soon as it possibly could makes me confident that single celled life is pretty common in the universe.

I've seen and heard the "earth's history represented as a year" analogy multiple times, but this is the first time I've seen it explained in reverse chronological order like this. Gives a fresh new perspective when visualizing those watershed moments in our planet's history in reverse. Well done!

I'm surprised that LUCA is already Feb... That's basically as old as earth itself. It also gives sense of how life grew exponentially.

I really like how they kept up the calendar scale throughout the video, it really gives an easy reference to how old certain things are. Good job guys.

This was the best explanation of uranium dating I've ever heard. It's also cool to learn that I live near some of the oldest crust material existing right now.
