A Fediverse community for open-ended, thought provoking questions

Rules: (interactive)

1) Be nice and; have fun

Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them

2) All posts must end with a '?'

This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?

3) No spam

Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.

4) NSFW is okay, within reason

Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either [email protected] or [email protected]. NSFW comments should be restricted to posts tagged [NSFW].

5) This is not a support community.

It is not a place for 'how do I?', type questions. If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email [email protected]. For other questions check our partnered communities list, or use the search function.

6) No US Politics.

Please don't post about current US Politics. If you need to do this, try [email protected] or [email protected]

Reminder: The terms of service apply here too.

For life in general I would agree but for human level intelligence I'm not so sure, in our galaxy anyway. The number of things that had to line up for us to be the dominant lifeform on the planet is enormous.

Goldilocks zone. Life. Large outer gas giants. Complex life (someone correct me if I'm wrong but I believe this has only happened once in 4B years / all complex lifeforms have a common ancestor) Oxygen tolerant life. Hundreds of millions of years of evolution. Multiple mass extinctions. Planet habitable for enormously long periods. Evolution of large brains for the first time. Etc
