Question: are aliens real?

Michael Schubert answered on 11 Mar 2020:

Nobody knows for sure, because there is a lot of outer space left to explore. We haven’t even been able to fully explore the planets closest to us, so who knows what is out there to discover?
Alien life is certainly possible. We have predicted that there are lots of planets in our universe that can support life, and we also know that life can grow under even the harshest conditions – in fact, there is some life on Earth that is so different to us, it seems almost alien. However, we’ll have to do a lot more exploring before we know for sure whether or not there are aliens out there!
