Just came across this video of Neil deGrasse going off about space travel, climate change, life, chimpanzees, and aliens, naturally. I’m usually not one to jump on a band wagon so quickly, but last night, half-asleep at two in the morning, I really liked this theory that life on Earth was spawned by rogue asteroid debris from an impact on the surface of Mars. He says early Mars had the same life-sustaining qualities that eventually formed on our planet, and some Mars-grown bacteria might’ve latched onto an Earth-bound chunk of space rock a few billion years back. KABLAM, life begins on Earth. It’s sort of neat to think that all the life on this planet was the result of a lucky accident.
In the morning, I thought a little more about this theory, and I found some holes.
If we’re all evolved spores from a Martian life-form, then where did the life on Mars come from? What asteroid brought the organisms to the surface of our neighboring red planet and where did that asteroid come from? It seems like another hollow theory when you think about it for long enough. You end up with the same questions and answers that lead to more questions. This is also my problem with the theories regarding the birth of the universe, both scientific and religious.
We came from a giant explosion. Who lit the fuse? We were created in seven days by God. Who made God?
(Insert other theory here, counter with similar roundabout question).
I don’t think we’re supposed to know. In some lights, this sucks. It would be cool to know how it all started. In another light, it’s more fulfilling to just recognize that you’re part of this big mystery. Don’t look up at the stars for the want of answers, but look up at the stars and know that you’re just as puzzling to them as they are to you. No one knows what the hell is going on in this wild, crazy universal party. We don’t even know who invited us to the party. We’re just here to drink beer, build the tallest skyscraper, and draw trees on paper. I’m sure if there is life on other planets in other galaxies, they’re doing pretty much the same thing.
Here’s the video of Neil deGrasse that I watched:
