Is being in a "habitable zone" enough to say the planet is habitable for human life? what characteristics would an earth-like planet need to have to support life? what challenges would we face traveling to and colonizing kepler-186f, or other earth-like planets outside of our solar system? do you think scientists should spend time looking for earth-like planets before we have the technology to visit them? why or why not? no response(s) be the first to respond to the discussion topic!

I belive the answer to the first one is no I would have to assume a habitual zone is one area on a planet. for example, an air conditioned building vs. the Savvanah dessert. However I am not sure maybe other answers will help more on this one. Sorry Earth-like planet would of course need water, plant life, animals, oxygen, fossil fuels etc. A challenge we would face on a travel to another liveable planet: do we have engough transportation? engough fuel to make it? How long can we live on this planet? Who or what else is present here? etc. Yes I do think they should discover a planet with earth like qualities befor investing in tools to get us to them. So money is not wasted. (make sure to put this into your own words )

In my opinion a habitable zone doesn't mean anything because It could just be an area where things come and go. Also it doesn't necessarily mean it’s safe for humans. In order for it to be habitable for humans the planet would need to have to be able to support life, it would need a reliable large source of water. It would also need a source of oxygen and there would need to be a way to plant food/grow food which would also mean that it would have to have good soil to grow it in. Some challenges that we might face during traveling are long distance and it would take a while to get their supplies together and by the time they get it would take even longer to do research and pick up samples. On the other hand I would say it’s a good idea to start looking for Earth-like planets and start making the technology at the same time while looking for other planets so that we don't waste as much time. For example if we find a planet then we would have to wait even longer to get the technology.
