Curious Kids: We have been trying to contact aliens – but do they want to contact us? |
This is a
great question – and the truth is that we don’t know the answer.
For
starters, we haven’t found any aliens yet, so we haven’t been able to ask them
and receive a reply. When we try to answer the question “Do they want to
contact us”, we have to put ourselves in their shoes – that is, if they have
feet.
The
question presumes that aliens do exist. And again, because we haven’t found any
yet, we don’t know if they do. It is possible they may exist, for one simple
reason: we exist. Whatever made the likes of bacteria evolve into complex
bodies with intelligent brains on Earth may have also occurred on another
planet.
If there are aliens out there, they might want
to contact us for the same reasons we want to contact them.
One reason why scientists on Earth are
looking for aliens is that we are curious. We want to know if they exist, what
they are like, and what our relationship with them might be. Curiosity is a
powerful force, leading us to look beyond the horizon and to try new things. It
is how we have developed science and technology, why we can have video calls
with friends on the other side of the world, and why we can now venture out into
space. Aliens may be curious about us, too.
But there are other reasons why we want to
contact others. We have sometimes needed help from others or companionship.
Perhaps aliens, too, would look to us for help or friendship.
They may also be interested in our planet.
Earth has perfect conditions for life. Aliens might need another home, if for
some reason – such as climate change, nuclear war, or an enormous asteroid
impact – they had to leave their own planet.
It’s also possible that they would not be
looking for friendship. There are plenty of examples from our history of times
when humans have traveled somewhere on Earth and acted cruelly, killing or
enslaving the people that lived there. Aliens settling on Earth might want us
out of their way. There’s another reason – humans are predators who eat other
lifeforms. Aliens might find us nutritious or tasty too.
These are all possible reasons why aliens
might want to contact us. But what if they didn’t? Some aliens might find us
boring, hard to understand, too primitive to deserve their attention, or
potentially bearing disease. Conversations across the vastness of space take
many years and travel much longer still. Some aliens might simply not be
interested in life beyond their own world.
