Are we alone?

When asked the question, “Are there any other lifeforms that occupy somewhere other than Earth,” I would say yes. I say this because there are lots and lots of other planets and stars. I would think it would be a pretty small chance that there are no other types of life somewhere out there. Mars was even suspected to have some type of life in the past. I think it will be very hard to see if there are any lifeforms because they could be so far away from us. Even if these lifeforms are the smallest unit of life, I believe that there are living things somewhere other than Earth.
