Do you think humanity will ever create colonies on the other planets (not just couple of trained astronauts but a civilian population in a city or something similar) and depending on your opinion why not / where and when do you think they're likely to be created first?... also will the frontier of colonising be in our own solar system on Mars for example or on some exoplanet
No it won't. Civilization will face major wars and problems during this century and space programs will get halted eventually. People don't want to fund something they don't even believe anymore (flat earth). There will be more entertainment and people are already seeking mainly pleasures, especially in the west, they don't want to achieve anything anymore.
