Can aliens tie knots?

Yes. A very basic skill if you have to tie something together, like a safety tether or a broken wire. Or the Captain’s feelers during a mutiny.

You have an anthropocentric viewpoint.

If we learned anything from Star Trek, Star Wars, and Alien, creatures from other planets may be nothing like humans.

“Knots are a important for… animal interactions, restraint,,.” -Really, don’t ascribe how you beat your animals or how you conduct your sex life with how aliens have evolved.

Are arms/hands/fingers assumed for this mind project?

Knot unless they have some kind of hands.

Excuse me. Yes , these hypothetical aliens have ‘arms and some type of flanges.)

Well, I was making a silly pun, but then yes, absolutely, they can and probably do tie knots. Even for aliens it’s knotworthy skill.

It happens to be their favoured method of contraception

Well, if an alien can’t tie this indispensable knot of horsemanship they won’t be riding the range here. lol

If one supposes that mastery of language and communication were also a vital prerequisite for space-faring, then it’s obvious – at least to this observer – that we’ll never do much more than revolve around our own planet for quite some time to come.

HAHA.
We INVENTED the knot, and taught early humans how to use them.
You would still be delousing each other in trees if not for us.

A more significant question would be whether or not it were possible and safe to have a fire (that’s not going to happen on a water world). You’d need an oxygen content above 10% and less than 35%. You’d need that in order to have metallurgy, and you’d need metallurgy to make knives or scythes to cut down your fibrous plants, and axes to cut down trees for your ships’ timbers. You could do that with stone tools, of course, but you’d play hell assembling a ship which would withstand the rigors of blue water sailing in stormy seas—without metal for the knees, futtocks and the bolts to hold the strakes to the ribs.

@Setanta futtocks, strakes, ribs, clearly I am “naut” ship terminology savvy, I must now look up the meanings of these curious words. haha

Throw in scantlings, too.

May I ask how this question came to exist?

We are making the assumption that for aliens the physical reality of a knot exists.

@Magical_Muggle The OP, @MrGrimm888 is wondering if aliens are appropriately capable of participating in bondage and restraints.

Necessity is the mother of invention.

So, if you’re presuming a waterworld, then the first time some idiot tied a granny knot and the boat drifted out to sea, they would quickly deduce that mandatory teaching of the half hitch and a proper square knot were required of anyone traveling by boat.

I think they’d get the hang of it pretty quickly. It sure beats building another boat each time some idiot let’s one just slip out to sea because they can’t tie a damn knot :)

It depends whether they have a thumb or not

Majical muggle, Ivery always been facinated by the possibility of aliens having to do normal things. The ways they overcome normal problems is particularly of interest to me. Knots are one of many things we don’t put much thought into. But they are extremely useful. I don’t think humans would have gotten this far without them. I wonder , as I’ve said, is knot tying a nessecary technology or stepping stone if a race has intentions of exploration of its planet and eventually it’s solar system and beyond?
PS, when I used the word restraint, I meant like tethering livestock or police using hand cuffs. Not bondage….
