I wrote a post which targets the “and how do we know that?” part of this question.
Full post here which has elaboration and examples for each of the types. Headings for the argument/evidence types:
1. Our understanding of the laws of physics says it should be possible. (Argument from Physics/Basic Science) 2. Nature has done this, so reasonably we as intelligent beings in nature should eventually be able to too. (Argument from Nature) 3. We have a proof of concept. (Argument from POC) 4. We’ve done it already. (Argument from Accomplishment)
The post also includes a couple of paragraphs on where these arguments fall short and how they’re stronger in the case of long-term space colonization.
