People have been attempting to contact aliens for a few years, however do the aliens need to contact us? – Sai, aged eight, London, UK
This can be 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 capable of ask them and obtain a reply. After we attempt to reply the query “do they need to contact us”, now we have to place ourselves of their footwear – 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 doable they could exist, for one easy purpose: we exist. No matter made the likes of micro organism evolve into advanced 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 out of the blue some 700 million years in the past. At the moment the Earth was already virtually 4 billion years previous, and had been inhabited by easy lifeforms similar 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 may need to contact us for a similar causes we need to contact them.
One purpose 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 power, main us to look past the horizon and to attempt new issues. It’s how now we have developed science and know-how, why we are able to have video calls with mates on the opposite facet of the world and why we are able to now enterprise out into house. Aliens could also be inquisitive about us, too.
However there are different explanation why we need to contact others. We now have generally wanted assist from others, or companionship. Maybe aliens, too, would look to us for assist or friendship.
They could even be curious about our planet. Earth has good situations for all times. Aliens would possibly want one other house, if for some purpose – similar to local weather change, nuclear struggle or an infinite asteroid impression – they needed to go away their very own planet.

It’s additionally doable 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 folks that lived there. Aliens deciding on Earth would possibly need us out of their method. There’s one more reason – people are predators who eat different lifeforms. Aliens would possibly discover us nutritious or tasty too.
These are all doable explanation why aliens would possibly need to contact us. However what in the event that they didn’t? Some aliens would possibly discover us boring, arduous to know, too primitive to deserve their consideration, or doubtlessly bearing illness. Conversations throughout the vastness of house take a few years, and journey for much longer nonetheless. Some aliens would possibly merely not be curious about life past their very own world.
Then again, it could be that life similar 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.
