It’s really possible that there are some other life forms out there, but they are much more likely to exist as microorganisms and not carbon-based, like life on Earth!
Aliens, as they are portrayed in films though, are less likely to exist and are a human invention..
Aliens definitely exist – NASA are looking for water on Mars! If they find water, that means that life can be there too! That’s also one of the reasons they really want to go to Titan and Europa which are moons of Saturn and Jupiter and which have water! These aliens are probably microbes though (bacteria and stuff).
.
If you’re looking for the type of aliens in films then that’s more difficult. There’s also a chance that alien civilisations exist on different planets, in different star systems! However, astronomers have been looking for space-faring civilisations (the type of alien that would fly a UFO) and they haven’t found any evidence for them (we haven’t heard transmissions and messages emitted from).
.
I’m personally hopeful that aliens are out there and that humanity will meet them one day! Maybe we’ve already met them but we simply can’t comprehend what they are or how they communicate!
