Summary

Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we'll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true.

0:00.0	Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,
0:05.2	we're asking the reason alien civilizations might be rare is because most aliens are huge.
0:10.5	To hear it and every episode early and add free, plus hours of bonus content, check out
0:15.5	go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.3	This episode is sponsored by Brilliant.
0:23.4	We often say humanity's future is out among the stars, but what if humanity's past was too?
0:42.6	Back in the 17th century, Nicholas Steno, a Danish scientist with a heavy interest in anatomy and geology, and later a Catholic bishop, noted that there was a connection
0:47.4	between the age and depth of fossils. This gave us the law of superposition that the higher
0:53.5	layers of geological strata are younger than the layers they sit on, and the law of superposition that the higher layers of geological strata are
0:55.3	younger than the layers they sit on, and the principle of original horizontality that
1:00.2	layers of strata form as thin horizontal sheets.
1:04.5	That seems incredibly obvious to us nowadays, but was quite the conceptual revolution
1:09.5	at the time.
1:11.0	It sparked a bigger one, as the sheer number of layers began strongly implying the planet
1:16.1	we dwelt on was a lot older than we thought.
1:19.5	A world predating human history by eons makes sense now, but the time it was beyond absurd.
1:26.9	Needless to say, this vastly older world and universe being unveiled set the stage for
1:32.3	Darwin as you could start seeing connections between fossils and modern life, converging
1:37.9	back to some original but different critters.
1:41.3	This actually caused a bit of a problem since around this same period we will begin
1:45.4	to get microscopes and realizing that there were a lot of very small organisms and that
1:50.7	many others were not appearing effectively by spontaneous generation or abiogenesis, like
