Blog #3 - Are non carbon based life forms possible?

Are non carbon based life forms possible? Why or why not? Give at least two reasons to support your answer.


I don't think non carbon based life forms are not possible. If non carbon based life forms were ever possible, why wasn't there ever any sign of it? Also if non carbon based life forms were possible, astronauts would have seen them when they go to space. So that concludes that non carbon based life forms are not possible.
