How can we tell if far-away distant objects in space are of/from alien life or not?

The first known interstellar object to visit our solar system was an object which they named ʻOumuamua, discovered on October 19, 2017. It was classified as an asteroid until new data showed that it behaved more like a comet. It was said that it is impossible to know what makes up ʻOumuamua, so how could we tell if objects like these in space are of/from alien life or not?

Well, at the least, there is no reason to make such an assumption without some sort of reason to do so. Simply coming from outside the Solar System isn't sufficient.

The more observations we can make, the more we are likely to learn. That means detecting such objects earlier. That is certain to happen over the next years as we operate more and faster survey telescopes.

You might expect ET to phone home but what type of signal could be used and where would it be aimed?
