Topic | Do you think the Rare Earth Hypothesis is true? |
candyapplered 07/14/18 11:19:33 PM #16: | Simple lifeforms are probably common, It's the complex ones that might be rare. Since our own planet's history is all we have to go on, it's not unreasonable to think it would be rare IMO. A comet here, a super-volcano there and any chance of complex life is either sent back to square one or ended permanently. --- too crazy for boys town, too much of a boy for crazy town ...
