Evidence 1: "Mars is the most likely planet for us to colonize"
Evidence 2: "The technology we would need to develop to send humans to Mars would directly benefit our economy here on Earth."
Evidence 3: "Studies have shown that radiation levels on Mars are not lethal to humans. Sure, we would have to live in a dome at first, but over time, we could use science to change the atmosphere and make it possible to go outside, just like on Earth!"

Evidence 1: "...it is too dangerous. The atmosphere of the planet is more carbon dioxide than oxygen, and it’s very cold.
Evidence 2: "Also, going to Mars would be very expensive."
Evidence 3: "that does not mean they aren't dangerous." "It is foolish to think a dome would be able to protect us from all of the radiation."
