If you don't subscribe to evolution leave now. It is part of the assumptions for my argument, and evolution vs. intelligent design vs. creationism is a different topic lol.

Anyways. Way way back in the day (some of you might remember) about 6 buhzillion years ago, we had a noxious, volcanic atmosphere of things such as cyanide and sulfur. Out of this mess it is theorized that amino acids, nucleic acids, and the likes were spontaneously formed (can be done in a lab in good conditions). These were the building blocks for structures of organic molecules that eventually became anaerobic bacteria. These anaerobic bacteria digested a lot of that other crap and produced O2. Over another buhzillion gerzillion trillion years, O2 became a major component of the atmosphere. Which gave rise to aerobic bacteria, which over the next 10x10^99230948234 years evolved into sentient life and eventually humans.

I would argue that from our perspective, our evolution into humans has been a net positive for us, no? I personally, would rather be a human than a bacteria... The top three reasons being- adult soda, adult bedtime, and regular bed time, if you get my drifts.

Anyways. What I'm wondering is... what if we changed our atmosphere into CO2 and life found a way (as it always has)? Life is always getting BETTER at survival, not worse (please don't bring up the modern medicine and ethics is de-evolving humans arguments YET). So what if by preventing CO2 build up we are preventing POSITIVE climate change, POSITIVE evolution, and POSITIVE benefits we can't know about?

Arguably we are destroying most life on the planet. Since we, too, cannot survive in a CO2 hot box, wouldn't it maybe be better for Earth if we moved down to caves and made our own little bubbles and niches, like the anaerobic bacteria, and let the Earth grow, repair and progress as it sees fit?

All I'm saying is that life began, changed the atmosphere, evolved, moved on, etc. Who's to say it won't/can't/shouldn't happen again? For all we know we could be replaced by elemental beings 4000x smarter than us.

No I'm not a Nazi, and we shouldn't kill off the human race, but weird to think about right?
