Are aliens and ufos scientifically real?

We don't know for sure, but we want to believe.

Explanation:

Outer space is a vast expanse that we have so much more to learn about, which is why it's hard to flat-out deny the possibility that other intelligent lifeforms exist. New species are continually being discovered in the ocean, and some animals thought to be long gone have emerged from the thick cover of jungles and the deep sea to be rediscovered.

probably yes, but they aren't really called aliens or how we think they look like there are obviously other creatures than us across the university and in parallel worlds and invisible creatures and etc. and there are creatures similar to humans slightly called greys they live in the layers of the earth they are the ones who own those so called "ufos" you can look them up! search greys creatures.
