The decision to visit planets other than earth is not supported by everyone. An individual that would argue against sending humans to other planets would be most reasonable in explaining that…

• water and food cannot be brought into space and the trip would be too long

• the process is very expensive and alien life would not welcome human contact

• the process is very expensive and it would be difficult to support human life for such a long journey

• humans cannot survive the journey into space and the process is very expensive
