I do, our earth is in a place in our system where it is not to cold or too hot. (A.K.A the goldilocks zone.) And that is just our system. So since there are thousands of trillions of other galaxies, I belive there are more in the goldilocks zone. But in order to find them, we will have to travel multiple light years.So long story short, yes, I do believe we have other life forms.
