Endless theories suggest how life may have begun on earth.
Be it a benevolent creator, an asteroid, or even a giant spaghetti monster. [a giant spaghetti monster in a populated street]
But Urey and Miller tried to show how organic life could start without religion or sentient
In 1952, they filled a flask with carbon dioxide, nitrogen, hydrogen sulfide, and sulfur dioxide. [chemical substances added to a erlenmeyer flask]
And in the tradition of all great mad scientists, they zapped it to life with electricity.. zapped it until it tried to come[frankenstein monster zaps an erlenmeyer flask with electricity and breaks]
After the experiment was complete, they discovered the flask now contained amino acids. [erlenmeyer flask with amino acids]
The point was not to start with organic molecules...
As a matter of fact, all of the component molecules were deader than Eddie Murphy’s
And Urey and Miller didn’t quite produce prokaryotic cells.
They weren’t full-on Frankensteining. [Erlenmeyer flask shatters and turns green]
But just because they didn’t raise a man from the dead, you definitely wouldn’t call
Quite the contrary.
The experiment is considered a landmark piece of research indicating that organic life,
under the right conditions, could have begun inorganically. [Rocks in a puddle and a turtle appears]
They’d provided a theory for the origin of life, without a single reference to witchcraft
or ancient aliens.
That means that B is the correct answer.
