It is a nice query – and the reality is that we don’t know the reply.
For starters, we haven’t discovered any aliens but, so we haven’t been in a position to ask them and obtain a reply. Once we attempt to reply the query “do they need to contact us”, we’ve got to place ourselves of their sneakers – that’s, if they’ve toes.
The query presumes that aliens do exist. And once more, as a result of we haven’t discovered any but, we don’t know in the event that they do. It’s potential they might exist, for one easy motive: we exist. No matter made the likes of micro organism evolve into complicated our bodies with clever brains on Earth could have additionally occurred on one other planet.
On Earth this transformation appears to have taken place fairly all of the sudden some 700 million years ago. At the moment the Earth was already nearly four billion years outdated, and had been inhabited by easy lifeforms equivalent to micro organism for a lot of that point. Why did it not occur sooner? And what made it occur? Till we discover the solutions to these questions we can not inform how seemingly it’s that it additionally occurred elsewhere.
If there are aliens on the market, they could need to contact us for a similar causes we need to contact them.
One motive why scientists on Earth are in search of aliens is that we’re curious. We need to know in the event that they exist, what they’re like, and what our relationship with them could be. Curiosity is a strong pressure, main us to look past the horizon and to strive new issues. It’s how we’ve got developed science and expertise, why we will have video calls with associates on the opposite aspect of the world and why we will now enterprise out into area. Aliens could also be interested in us, too.
However there are different the explanation why we need to contact others. We have now typically wanted assist from others, or companionship. Maybe aliens, too, would look to us for assist or friendship.
They might even be curious about our planet. Earth has perfect conditions for life. Aliens may want one other house, if for some motive – equivalent to local weather change, nuclear conflict or an infinite asteroid affect – they needed to go away their very own planet.
It’s additionally potential that they might not be in search of friendship. There are many examples from our historical past of occasions when people have travelled someplace on Earth and acted cruelly, killing or enslaving the those that lived there. Aliens selecting Earth may need us out of their manner. There’s another excuse – people are predators who eat different lifeforms. Aliens may discover us nutritious or tasty too.
These are all potential the explanation why aliens may need to contact us. However what in the event that they didn’t? Some aliens may discover us boring, exhausting to know, too primitive to deserve their consideration, or doubtlessly bearing illness. Conversations throughout the vastness of area take a few years, and journey much longer still. Some aliens may merely not be curious about life past their very own world.
Alternatively, it could be that life equivalent to ours is definitely quite common. With so many worlds and civilisations to select from, we could merely not but have caught their eye. If that’s the case, we would quickly detect alien life round close by stars for ourselves.
